Two colours, honestly mapped.
This is the instrument this site's own imagery goes through: a photograph reduced to one tonal ramp between two colours of the palette. It runs entirely in your browser: the image never leaves your device, and it reports the real encoded size of every export, because a beautiful file that is too heavy to ship is not finished.

Processing happens on a canvas in your browser tab. No upload, no storage, no analytics event on the image or video itself. The PNG is lossless by format; the WebP is encoded at the quality you set, with the true file size shown before you download.
