How to use it

Upload photos, choose the dark and light color, and adjust strength. The browser builds the two-color result on your device.

Pair a dark blue or green with a light yellow or pink for clear poster-style images. Lower the strength if faces become too flat.

Your files are not uploaded to a server. The editor runs in your browser with local libraries from this site.

Large images can take longer on phones. If the browser slows down, process fewer files at once or choose a smaller output format.
