Basic Everyday Calculators
These are the calculators for sums you could do on paper but would rather not do in front of other people: what the tip should be, what a jacket actually costs after the sale sign, what percentage of the total one figure represents. Shoppers, diners, parents helping with homework and small traders use them daily. The Tip Calculator adds a chosen percentage and divides the bill between however many people are at the table, which removes the usual rounding argument. The Discount Calculator turns a headline reduction into the price you will pay, and works in reverse when you want to know what a marked price implies about the original. The Percentage Calculator covers the three forms of the question people mix up: a percentage of a number, one number as a percentage of another, and the percentage increase or decrease between two figures. The Fraction Calculator adds, subtracts, multiplies and divides fractions and reduces the result, which helps with recipes and with school work where the answer has to stay a fraction. The Average Calculator takes a list of values and returns the mean, useful for marks, readings and monthly bills. Each tool works in the browser as you type, with no sign-up and nothing stored.
5 toolsmedia file converter
Media converters deal with clips that are in the wrong format or the wrong size for where they are going: a podcast recorded as video, a lecture too large to email, a short scene that has to loop silently in a post. Students, podcasters and social media managers are the usual users. mp4 to mp3 extracts the soundtrack from a video and leaves you with an audio file a fraction of the size, which is the right tool for turning a recorded talk into something you can listen to on a commute. mp4 to gif does the opposite kind of reduction, converting a few seconds of footage into a short looping animation that plays inline anywhere an image does. When the format is already right but the file is too heavy, the video compressor lowers the bitrate and resolution to fit a sharing limit while keeping the clip watchable. For changes to the content itself, the mp4 video editor covers trimming, joining and reordering scenes, and the mp3 editor cuts intros, silences and overlong pauses out of audio. A typical run is to edit first, then compress or convert last, so that you are not re-encoding material you were about to cut anyway.
5 toolsScientific & Math Calculators
This group covers the maths that goes beyond arithmetic: functions, geometry and the summary statistics behind a data set. Students, teachers, lab technicians and anyone checking a spreadsheet formula by hand are the people who need them. The Scientific Calculator is the general instrument, with trigonometric functions, logarithms, exponents, roots, constants and bracketed expressions evaluated in the proper order. It replaces a handheld unit for homework and quick checks, and it is the right place to start when your problem is an expression rather than a shape or a sample. The Triangle Calculator solves for the missing sides and angles once you supply enough known values, applying the sine and cosine rules and returning area and perimeter along the way. That saves choosing the right identity yourself, and it suits geometry coursework, surveying sketches and anything involving a sloped measurement. The Statistics Calculator takes a list of numbers and reports mean, median, mode, range, variance and standard deviation together, which is more useful than a single figure because the spread usually matters as much as the centre. Paste readings straight from a table and read the summary off in one pass. All three calculate in your browser, with no sign-up and nothing sent to a server.
3 toolsFinance Calculators
Finance calculators answer the questions that decide whether a plan is affordable: what a repayment costs each month, what a pot of money grows into, and what is left after tax. They suit anyone weighing up a purchase, a move or an investment before talking to a lender or an adviser. For borrowing, the Loan Calculator gives the monthly payment and total interest on a personal or car loan, while the Mortgage Calculator handles longer terms and lets you see how much a shift in rate changes the payment over twenty-five years. On the saving side, the Compound Interest Calculator shows what regular contributions turn into over time, and the Savings Calculator works backwards from a target so you know what to put aside each month to reach it. The ROI Calculator compares what an investment returned against what it cost, which is the quickest way to rank two options against each other. The Tax Calculator estimates what comes off an amount before it reaches you, and the Currency Converter puts a foreign price into familiar money. A common order is to convert or tax-adjust the figure first, then feed the realistic number into the loan or savings tool. Each one runs in your browser, with no account and nothing sent anywhere.
7 toolsHealth & Fitness Calculators
Health and fitness calculators turn height, weight, age and activity level into the numbers people actually train and eat by. They suit anyone starting a programme, tracking progress between weigh-ins, or simply checking whether a target they have been given is reasonable. The BMI Calculator is the usual starting point, giving a single figure and the band it falls into. It takes no account of muscle, so pair it with the Body Fat Calculator, which uses circumference measurements to estimate composition and gives a fairer picture for anyone who lifts. The Ideal Weight Calculator provides a range for your height rather than one number, which is more useful as a goal to move towards. For daily habits, the Calorie Calculator estimates the energy you burn and the intake that would maintain, lose or gain weight at a chosen rate, and the Water Intake Calculator suggests a fluid target based on body weight and how much you train. A sensible order is to measure first with BMI or body fat, set a target with the ideal weight range, then use the calorie figure to plan meals around it. Results are estimates rather than medical advice. Everything runs in your browser with no account and nothing recorded.
5 toolsDate & Time Calculators
Date and time calculators answer questions that are awkward to do in your head because months vary in length and leap years get in the way. They come up in project planning, visa and contract paperwork, event organising and anything involving colleagues in other countries. The Date Difference Calculator counts the interval between two dates in days, weeks and months, which is what notice periods, residency applications and rental agreements usually ask for. The Age Calculator is the same arithmetic aimed at birthdays, giving an exact age in years, months and days as of today or any date you choose, and it is the quicker option when you just have a date of birth. The Time Zone Converter maps a moment in one place to the local time somewhere else, including the daylight saving shifts that make calls land an hour out twice a year. Use it before you send an invitation rather than after. The Countdown Timer tracks the remaining time to a fixed point such as a launch, an exam or a flight, and keeps running on screen while you work. All four run in the browser with no sign-up, and no dates you enter are stored anywhere.
4 toolsConstruction & Engineering
Construction calculators turn the dimensions written on a sketch or a tape measure into the quantities you actually have to order. Builders, landscapers, self-builders and anyone pricing up a job use them before buying materials, because over-ordering costs money and under-ordering costs a second delivery. The Area Calculator works out the surface of rectangles, triangles, circles and combinations of them, which is the figure behind almost every quote: flooring, turf, paint, plaster, paving and roofing are all sold by area. Awkward rooms are easiest handled by splitting the plan into simple shapes and adding the results, and you can work in metric or imperial units to match whatever the supplier quotes in. The Concrete Calculator goes a step further into volume, taking the length, width and depth of a slab, footing or post hole and returning the amount of concrete needed, in cubic metres or yards along with an indication of the bags or mixer loads that represents. Depth is where estimates go wrong most often, so measure it in several places on uneven ground and use the largest figure. The usual sequence is to calculate area first, then apply the thickness to get volume. Both run in your browser with no sign-up.
2 toolsBusiness Calculators
Business calculators answer the two questions that decide whether a product is worth selling: how much of each sale you keep, and how many sales are needed before the venture stops losing money. Small business owners, freelancers, market traders and anyone writing a plan for a lender need both figures. The Profit Margin Calculator takes your cost and your selling price and returns the gross profit and the margin as a percentage. That distinction matters, because a fifty per cent markup on cost is not a fifty per cent margin on the sale price, and quoting the wrong one makes a business look healthier than it is. The tool also works backwards, so you can set the margin you need and see what price it implies before you publish a list. The Break Even Calculator brings fixed costs into the picture. Given rent, salaries and other overheads alongside the per-unit cost and price, it tells you how many units must sell before the month is covered. Compare that number against what you realistically expect to sell, and you have a straight answer on whether the pricing works. Use them in order: set the margin first, then test the resulting price against break-even volume. Both calculate in your browser without sign-up.
2 toolsInternet & Digital Calculators
These two calculators translate between file sizes and connection speeds, which are quoted in different units and routinely confused. Anyone downloading a large file, planning a video stream or choosing a broadband package benefits from checking the figures before committing. The Download Time Calculator takes the size of a file and the speed of your line and estimates how long the transfer will take. It is the quick answer to whether a game update will finish before you go out, or whether a client can reasonably be sent a video rather than a link. Remember that speeds are advertised in megabits while files are measured in megabytes, an eightfold difference that the calculator handles for you. The Bandwidth Calculator works at the level of a connection rather than a single file. Give it the number of users or streams and the quality each needs, and it estimates the capacity required, which is what you want when sizing office internet, planning a live broadcast or working out whether a household can watch two 4K streams while someone else is on a video call. Use the download tool for one-off transfers and the bandwidth tool for sustained, simultaneous use. Both run in your browser with no sign-up and nothing recorded.
2 toolsUnit Converters
Unit converters translate a measurement from one system into another so that a recipe, a spec sheet or an overseas parcel label makes sense. Cooks, students, engineers and anyone reading instructions written for a different country use them constantly. If you already know the type of measurement, go straight to the specific tool. The Length Converter covers millimetres through to miles, the Weight Converter moves between kilograms, pounds, stones and ounces, and the Temperature Converter handles Celsius, Fahrenheit and Kelvin, including the negative values that trip people up. The Volume Converter deals with litres, pints, cups and gallons, and matters most in the kitchen where the American cup and the imperial pint differ. The Speed Converter switches between kilometres per hour, miles per hour, knots and metres per second, which is useful for driving abroad and for reading wind forecasts. The Data Storage Converter covers bits, bytes, megabytes and terabytes, and is worth reaching for whenever a file size and a quota are quoted in different units. When you are not sure which category a unit belongs to, open the general Unit Converter and pick from the list there. All of them calculate in the browser as you type, with no sign-up needed.
7 toolsExpense Trackers
Managing money takes two habits: deciding in advance where it should go, and recording where it actually went. These tools cover both sides, and they suit households, students and freelancers with irregular income who want a clear picture without linking a bank account to anything. The Budget Planner is the forward-looking one. You enter income and then allocate it across categories such as rent, food, transport and savings, and it shows what is left over or where the plan is already short. It is the right place to start a new month, a shared household arrangement or a savings push, because it forces the allocation to add up before real money moves. The Expense Tracker is the backward-looking one. You log purchases as they happen and it totals them by category, which is how you find out that small regular spending is doing more damage than the occasional large bill. Over a few weeks it produces the real numbers your next budget should be built on. Used together, the loop is straightforward: plan in the planner, record in the tracker, then adjust the plan using what the tracker showed. Both run in your browser, with no account required and no financial details sent anywhere.
2 toolsTo-Do Tools
A to-do list is the simplest productivity tool there is, and the reason it survives every wave of more elaborate software is that writing a task down gets it out of your head and stops you carrying it around all day. The To-Do List here is deliberately plain. You add items, mark them complete as you go, and remove what no longer matters. There is no project hierarchy, no assignee field and no notification scheme to configure, which means the whole thing takes seconds to set up and nothing to learn. That makes it a good fit for a single day's work, a packing list before a trip, a shopping run, or the short set of steps left in a job you are part way through. It works best when you keep the list short and specific. Items phrased as actions, with a verb at the front, are easier to start than vague headings, and a list of six things you will genuinely do today is more useful than forty you might do eventually. Clear the completed items at the end of the day so tomorrow starts clean. It runs in your browser, needs no account and installs nothing.
1 toolsPomodoro & Focus Timers
Focus timers make a working session finite. Knowing that a stretch of concentration has a defined end makes it easier to begin, and the enforced pause afterwards is what stops a long day turning into a shallow one. Students, remote workers and anyone prone to drifting into a browser tab will recognise the problem. The Pomodoro Timer follows the established pattern of a working interval, commonly twenty-five minutes, followed by a short break, with a longer break after several rounds. Its strength is rhythm. The countdown acts as a commitment device for tasks you have been avoiding, and the break prompt stops you working past the point where the quality drops. It suits admin, coding, marking and anything that can be broken into small units. The Study Timer is the better fit when the work needs a longer continuous run, such as reading a chapter, sitting a practice paper or writing a section of an essay. You set the duration to match the task rather than to a fixed cycle, and you track the total time spent across a session. Pick the Pomodoro rhythm when starting is the hard part, and the study timer when interruption is the hard part. Both run in the browser without sign-up.
2 toolsQR Code Generators
A QR code turns something typed into something scanned, which matters wherever a person has your material in front of them but not in a form they can click. Restaurants linking to a menu, event organisers pointing to a schedule, shops sharing a review page and job seekers adding a portfolio link to a printed CV all use them for the same reason. The QR Code Generator takes the content you supply, most often a web address but also plain text, contact details or a Wi-Fi network, and encodes it as a square you can download and place in a design. A few practical points decide whether a code works in the wild. Keep the destination address short, since more data means a denser pattern that is harder to scan. Leave clear white space around all four edges, as printing right up to the border is the most common cause of failure. Print at a size suited to the reading distance, roughly a tenth of the distance across. Always scan the finished artwork with a phone before it goes to print, and test it under the lighting it will actually be read in.
1 toolsPassword Generators
Passwords people invent themselves follow patterns, and those patterns are exactly what cracking software tries first: a name, a date, a capital at the front and a digit at the end. A generated password has no such structure, which is why security guidance recommends one for any account that matters. The Password Generator builds a random string to your specification. You set the length and choose which character types to include, typically uppercase and lowercase letters, digits and symbols, then copy the result straight into the sign-up or password change form. Length does more for strength than complexity does, so if a site allows it, prefer a longer password over a short one stuffed with punctuation. Sixteen characters or more is a reasonable floor for email, banking and anything holding payment details. Generate a separate password for every account rather than adapting one across several. That way a breach at one site cannot be reused elsewhere, which is how most account takeovers actually happen. Since random strings are not memorable by design, store them in a password manager or, for the handful you must type from memory, use a long passphrase instead. The generator runs in your browser, so the password is created on your own device and never sent anywhere.
1 toolsNotes Tools
Note taking works best when there is no friction between having a thought and writing it down. An app that needs a login, a workspace and a choice of folder loses the thought before you reach the keyboard. The Notes App is built for that first moment of capture. Open the page and start typing: a phone number read out on a call, the points from a meeting, a paragraph you are drafting before it goes into a document, a snippet of text you need to hold while you switch between two other windows. It also serves as a scratch pad for cleaning up formatting, since text pasted in and copied back out leaves the styling of its original source behind. Because it is a single plain surface rather than a filing system, it suits short-lived notes rather than a permanent archive. Anything you want to keep should be moved into a document, an email to yourself or a proper note-taking application at the end of the session, and anything genuinely sensitive is better kept somewhere with a password on it. It runs in your browser, needs no account and installs nothing, which is what makes it available in the few seconds you actually have.
1 toolsFile Tools
File tools exist for the moment when a document is in the wrong shape for where it has to go: a form wants images, a printer wants a PDF, a colleague wants plain text they can paste into an email. They are useful for admin work, coursework and any filing system with strict upload rules. Pdf to text Converter pulls the words out of a PDF so they can be edited or searched, which is the right choice when you care about the content rather than the layout. Pdf to images keeps the layout instead, rendering each page as a picture you can drop into a slide or a chat. word to jpg does the same job for a Word document when the recipient cannot open .docx files. Going the other way, Image to pdf collects scans or phone photos into a single ordered document, which is how most receipt and ID uploads are meant to be submitted, and Text to pdf Converter turns a plain draft into something tidy enough to print or attach. The File Size Calculator helps before you send anything, converting between bytes, megabytes and gigabytes so you can tell whether an attachment will clear a size limit. Conversions run in the browser, with no account and no upload.
6 toolsCSV & Data Tools
CSV and JSON are the two formats data usually arrives in, and they suit different audiences: spreadsheets and finance teams expect CSV, while APIs and developers produce JSON. These tools let you move between them and inspect the result without opening a spreadsheet application. The CSV Viewer renders a file as a readable table with aligned columns, which is far easier to scan than raw comma-separated text. It is the quickest way to check an export before you import it somewhere: you can see whether the header row survived, whether a field containing a comma has broken the column alignment, and whether the row count looks right. That check takes seconds and saves reimporting a mangled file later. The JSON to CSV Converter flattens structured data into rows and columns so that an API response, a log export or a saved query result can be opened in a spreadsheet, charted or handed to someone who does not work with JSON. Nested objects are flattened into columns, so it is worth reviewing the output in the viewer before you pass it on. The natural workflow is convert, then view, then import. Both tools process the data in your browser, with no upload and no account needed.
2 toolsPDF Tools
PDF is the format documents are sent in when the layout has to survive the journey, which is exactly why it is awkward to work with afterwards. These tools handle the three things people most often need to do to a finished PDF. The PDF Merger combines several files into one in the order you set, which is how scanned pages, signed forms and separate chapters are meant to be submitted when an upload field allows only a single attachment. It is also the fix for a scanner that saved every page separately. The pdf editor changes the document itself rather than its packaging, letting you correct text, add a note or a signature, and remove or reorder pages without going back to the original source file. Use it when the wording is wrong or a page is in the wrong place, and use the merger when the content is fine and only the assembly is missing. pdf to jpg renders each page as an image, which is what you want when a page has to be shown inside a slide, a listing or a message thread where PDFs will not preview. The result is a picture, so it cannot be edited as text afterwards. All three run in your browser without sign-up or file uploads.
3 toolsImage Tools
Image tools handle the small jobs that sit between taking a picture and publishing it: getting the dimensions right, cutting the file size, changing the format or tidying up what is in the frame. Bloggers, shop owners, students and anyone emailing photos to a printer end up needing at least one of them. Start with the Image Resizer when a photo is too large for a page or a profile field, and the Image Compressor when the dimensions are fine but the file weighs too much for an upload limit. The Image Converter moves between formats in general, while Jpg to png and svg to png handle the two swaps people ask for most, one for transparency and one for turning vector artwork into a fixed-size bitmap. The Image upscaler works the other way, adding pixels to a picture that is too small to print. For content rather than format, the Image background remover isolates a subject against white or transparency, the Object Remover clears out a stray sign or passer-by, and the Watermark Tool stamps your name across work before you share it. The Image photoshop editor covers freehand edits, the Meme Generator adds captions, and screenshot to code turns an interface mockup into markup. Everything runs in your browser. There is no sign-up and no upload of your files to a server.
12 toolsText Tools
Text tools tidy up writing that is nearly ready: the word count is over, the capitalisation is inconsistent, a pasted list has repeated itself, or a long passage needs to be cut to a sentence or two. Writers, students, editors and marketers use them at the point of handing work over. The Word Counter reports words, characters and sentences, which matters when an essay has a hard limit or a meta description has to fit. The Case Converter switches a heading between sentence case, title case, upper and lower without retyping it, and is the fastest fix for text pasted out of a spreadsheet in full capitals. The Duplicate Line Remover cleans lists of emails, keywords or references where the same entry has crept in more than once, leaving one copy of each line in the original order. The Text Summarizer condenses a long article into its main points when you need the gist rather than the whole thing. Lorem Ipsum Generator fills a layout with placeholder copy so a design can be judged on spacing rather than wording, and the Text Reverser flips a string end to end, handy for puzzles and for checking palindromes. Nothing you paste leaves the browser, and no sign-up is required.
6 toolsColor Tools
Colour tools support the stage of a design where a scheme is being chosen and then written into code. Web designers, brand builders, slide makers and front-end developers move between them while settling on a look. Start with the Color Palette Generator when you have nothing fixed yet. It proposes sets of colours that work together, so you can judge combinations rather than single swatches, and it is the fastest way past a blank page. When one colour is already decided, perhaps from a logo or a photo, the Color Picker lets you select an exact shade and read off its value in several notations. The Hex to RGB Converter bridges the formats: hex codes are what designers exchange, but RGB values are what you need for transparency, for canvas work and for many design applications. Converting by hand is error-prone, so it is worth the extra click. The Gradient Generator blends two or more of your chosen colours and produces the CSS for the result, including direction and stops, which can be pasted straight into a stylesheet. A common sequence is to generate a palette, pick and refine one accent, convert it to the notation your code needs, then build a gradient from the pair. Everything runs locally in your browser.
4 toolsEducation & Learning
These study tools support the two stages of learning something: getting material into your head, and checking whether it stayed there. Students revising, teachers preparing a lesson and anyone training a practical skill will find a use for them. The Flashcard Creator is for the first stage. You write question and answer pairs and work through the deck, which suits vocabulary, formulae, dates and definitions where repetition is what fixes the material. Building the cards is itself part of the revision, because you have to decide what the question actually is. The Quiz Generator is for the second stage. It turns a set of questions into a test you can take or hand to someone else, giving a score at the end rather than immediate confirmation card by card. Use flashcards while you are still learning and a quiz when you want an honest measure of how much you know. The Typing Speed Test measures words per minute and accuracy over a timed passage, which matters for coursework, transcription work and job applications that quote a typing requirement. Repeat it over several weeks to see the trend rather than a single run. All three work in the browser without sign-up.
3 toolsDeveloper Tools
This is the set of small utilities a developer reaches for several times a day, usually while debugging something else. Rather than installing a package or writing a throwaway script, you paste the data in, read the answer and get back to work. The JSON Formatter indents and validates API responses so a missing bracket becomes obvious, and the SQL Formatter does the same for queries that arrived as one long line. The Regex Tester shows which parts of a sample string a pattern actually matches, which is far faster than guessing in a log file. The Diff Checker highlights what changed between two versions of a config or a paragraph of text. For data that has to survive being moved around, use the Base64 Encoder/Decoder for binary in a text field, the URL Encoder/Decoder for query strings and the HTML Encoder/Decoder when markup needs to be shown rather than rendered. The Cron Expression Generator translates a schedule into the five-field syntax and back again, and the CSS Minifier strips whitespace before deploy. The Markdown Editor previews as you type, and html javascipt css compiler gives you a scratch pad for a quick front-end idea. Heavier work belongs in the Python compiler, which executes your script and returns the output.
12 toolsSecurity Tools
These utilities cover the routine security checks that come up in development and system administration: confirming that a file arrived intact, producing an identifier that will not collide, and judging whether a password is worth using. The SHA256 Hash Generator is the one to reach for when the hash matters. It produces the digest used to verify downloads, sign data and store credentials, and it is what current guidance expects. The MD5 Hash Generator remains here because plenty of older systems, checksum files and legacy APIs still quote MD5 values that you need to reproduce and compare. Use it for matching against existing checksums, not for anything protecting real secrets. The UUID Generator produces universally unique identifiers for database rows, test fixtures, filenames and message keys, which saves inventing a scheme of your own and avoids clashes when records are merged from several sources. The Password Strength Checker estimates how resistant a candidate password is, flagging length, predictable substitutions and common patterns, and is best used while you are still choosing rather than after an account exists. Run it on a draft password rather than one already in service. The calculations happen in your browser, so nothing you type is transmitted or stored.
4 toolsAI & Automation Tools
These two writing tools handle the difference between text that is wrong and text that is merely clumsy. Students, non-native English writers, marketers and anyone sending work to a client will use one or the other before pressing send. The Grammar Checker reads a passage and flags errors of correctness: agreement between subject and verb, tense slips, misplaced punctuation, missing articles and the spelling mistakes a dictionary alone will not catch because the wrong word is still a real word. It is the last pass before publishing, and the one that protects you from the mistakes readers notice first. The Text Paraphraser rewrites a passage in different wording while keeping the meaning. That is useful when a sentence is grammatically fine but reads awkwardly, when you want a formal draft to sound plainer, or when you need to express a source in your own words rather than quoting it. Always read the result rather than accepting it, because rephrasing can shift emphasis and a paraphrase of someone else's work still needs a citation. A sensible order is to paraphrase first, while the wording is still in flux, and to run the grammar check last on the version you intend to send.
2 toolsRandom Generators
Random generators settle things that nobody should have to argue about: who goes first, which name to use, what number wins the raffle. Teachers, game masters, competition organisers and writers stuck for an idea all keep one open. The Random Number Generator is the general-purpose option, since you set the range yourself and can use it for a prize draw, a test data set or picking a seat number. For smaller, more physical choices, the Dice Roller reproduces the dice a board game needs when the set is missing one, and Coin Flip handles a straight two-way call. The Wheel of Fortune suits a group watching a decision being made, because the spin is visible and feels fair in a way that a printed number does not. The Name Generator produces names for characters, teams, pets or projects, and the Random Word Generator gives writing prompts, warm-up game material and vocabulary practice. Choose by how many options you have and who is watching: a coin for two, dice for a handful, the wheel for a named list, and the number generator when the range is wide. All of them draw the result in your browser, so there is nothing to install and no account to create.
6 toolsMini Games
Mini games fill the five or ten minutes between other things: a break between revision sessions, a classroom warm-up, a wait for a meeting to start. They load instantly and need no download, account or install. Tic Tac Toe is the quickest two-player option and works well on a shared phone screen, since a round takes under a minute. The Memory Match Game turns cards face down and asks you to find the pairs, which is a genuine recall exercise as well as a game, and it scales in difficulty with the size of the grid. Word Scramble gives you the letters of a word out of order and suits anyone practising spelling or English vocabulary. The Number Guessing Game hides a value within a range and narrows it with higher and lower feedback, which is a painless way to show children how a search by halving works. decision maker wheel game adds a competitive element to a spinner, turning a choice into a small event rather than a lookup. Pick by group size and mood: two players and a grudge suit Tic Tac Toe, solo focus suits memory and guessing, and a crowd suits the wheel. All of them run in the browser.
5 toolsTypography Tools
Typography decides how text feels before anyone reads a word of it, and these two tools cover the practical end of that: choosing a typeface, and building letterforms out of plain characters. The Font Preview Tool shows your own text set in different typefaces rather than the usual sample sentence, which is the only reliable way to judge a font. A headline made of your actual product name, a paragraph of your actual copy and the numerals you will really use reveal problems that a stock phrase hides, such as awkward letter pairs, weak digits or a lowercase that falls apart at small sizes. Compare candidates at the size and weight you intend to publish at, not at the default. The ASCII Art Generator converts words into large letters drawn from ordinary text characters, producing banners that survive anywhere only plain text is allowed. That makes it useful for terminal output, README headings, code comments, commit banners and message boards where images are stripped out. Different character styles change the weight and readability, so try a few and check the result in a monospaced context before using it. Use the preview tool when the medium renders fonts, and the ASCII generator when it does not. Both run in the browser with no sign-up.
