File 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.

File Size Calculator
Convert file size units, estimate transfer time at a given connection speed, and work out how many files fit on a drive.
Decimal units, binary units and the transfer formula
Transfer time depends on a second conversion, between bits and bytes. There are 8 bits in a byte, and connection speeds are quoted in bits per second while file sizes are quoted in bytes. The calculation is: time in seconds = file size in bytes x 8, divided by speed in bits per second. When a speed is entered in bytes per second, such as MB/s, the factor of 8 drops out and the tool divides size by speed directly.
The storage planner uses a simpler relation: total = size per file x number of files, and files that fit = capacity / size per file, rounded down.
Worked example: a 4.7 GB file on a 100 Mbps line
First convert the file to bits. 4.7 GB in decimal units is 4,700,000,000 bytes. Multiplied by 8, that is 37,600,000,000 bits. A 100 Mbps line carries 100,000,000 bits per second, so the transfer takes 37,600,000,000 / 100,000,000 = 376 seconds, which is 6 minutes and 16 seconds.
The same file on a 20 Mbps upload link takes five times as long: 1,880 seconds, or 31 minutes and 20 seconds. Entering the speed as 12.5 MB/s instead gives the same 376 seconds, because 12.5 MB/s is simply 100 Mbps expressed in bytes.
For the storage planner, suppose you are archiving 4.7 GB video files onto a 1 TB drive. 1 TB is 1,000 GB in decimal units, so 1,000 / 4.7 = 212.7, meaning 212 complete files fit with about 3.4 GB left over. Note that the drive reports 1 TB as 931 GiB in Windows, since 1,000,000,000,000 / 1,073,741,824 = 931.3.
Why real transfers are slower than the calculation
Wi-Fi adds another gap. An advertised wireless link rate is the radio's peak, not the sustained throughput, and walls, interference and older devices commonly halve it. For a realistic estimate on Wi-Fi, run a speed test and enter the measured figure rather than the number on your broadband contract.
Two mistakes recur. The first is confusing Mbps with MB/s: divide by 8 to convert, so 100 Mbps is 12.5 MB/s, not 100. The second is comparing a drive's advertised decimal capacity against the binary figure your operating system reports, and concluding that space has gone missing.
