Canvas pixels, CSS filters and the undo stack
The editor works on an HTML canvas. The uploaded picture is decoded into pixels, drawn onto that canvas, and every operation redraws it.
The adjustments are expressed as canvas filter values. Brightness, contrast and saturation run from 0 to 200 per cent, with 100 meaning unchanged, while saturation extends to 300 for stronger effects. Hue rotation shifts colours around the colour wheel between minus 180 and plus 180 degrees, blur is a radius in pixels up to 20, and sharpness runs from 0 to 100. The twelve presets are simply combinations of the same operations: noir, for instance, is full greyscale together with contrast at 145 per cent and brightness at 85 per cent.
Transforms are geometric rather than tonal. A rotation redraws the picture onto a canvas with its width and height exchanged for a quarter turn, and a flip redraws it mirrored. Crop redraws only the selected rectangle at its own size, and resize redraws the whole image at new dimensions, up to 8000 pixels on a side. Each committed step is pushed onto an undo stack.

Preparing a 4000 by 3000 photo for the web
Start with a camera photograph measuring 4000 by 3000 pixels, which is 12 million pixels and a 4:3 aspect ratio.
Open the resize panel, leave the ratio locked and type 1600 into the width. The height follows automatically: 1600 divided by 4000 is 0.4, and 3000 multiplied by 0.4 gives 1200. The result is 1600 by 1200, still 4:3, now 1.92 million pixels, or 16 per cent of the original pixel count.
The photograph looks slightly flat, so set brightness to 110 per cent and contrast to 115 per cent, then nudge saturation to 120. If you prefer a single click, the vivid preset applies saturation at 220 per cent with contrast at 110 instead.
Add a caption by clicking the spot where it should sit, choosing Impact at 48 pixels in white. Finally set the export format to JPEG for a photograph, or PNG if the picture is a screenshot with sharp text, and download the result at 1600 by 1200.

Working non-destructively and knowing the limits
Work in a sensible order. Crop and rotate first so you are not adjusting tones on pixels you are about to discard, then set brightness, contrast and saturation, then resize, and add text last so it is sized against the final dimensions. Text placed before a resize will be scaled along with everything else and may end up blurred or too small.
Once an operation such as a crop or a resize is applied, the canvas holds the new pixels. Undo and redo let you step back through your edits, and the restore option returns to the image as uploaded, but detail thrown away by shrinking an image cannot be recovered by enlarging it again, which only interpolates.
Choose the export format for the content. JPEG suits photographs but discards transparency and adds compression artefacts around sharp edges. PNG keeps transparency and stays crisp on text and diagrams at the cost of file size. WebP usually gives the smallest file at similar quality. This is a straightforward pixel editor: there are no layers, masks or selection tools beyond the crop rectangle.

Frequently Asked Questions
No. The image is decoded and edited on an HTML canvas inside the page, and the export is generated on your own device. Nothing is transmitted, so personal photographs, screenshots containing private information and unpublished work stay on the machine you are using.
Yes. Undo and redo step back and forward through your edits, with Ctrl plus Z and Ctrl plus Y as shortcuts, and a restore option returns the canvas to the image exactly as it was uploaded. Enlarging an image after shrinking it will not recover lost detail, though.
Keep the ratio locked and enter only the width or only the height; the other dimension is calculated for you. A 4000 by 3000 image set to 1600 wide becomes 1600 by 1200. Unlock the ratio only when you deliberately want to stretch the picture to fit a fixed space.
JPEG for photographs, where its compression is efficient and transparency is not needed. PNG for screenshots, logos and anything with sharp text or transparent areas. WebP usually produces the smallest file at comparable quality and is supported by current browsers, which makes it a good default for web pages.
Yes. Type your text, choose one of six typefaces including Arial, Georgia, Impact, Times, Courier and Verdana, set the size between 8 and 300 pixels and pick a colour, then click the point on the image where it should be placed. Add it after resizing so it renders at the right scale.
