Posterize photos locally by limiting color levels, with preview, exact level control and ZIP download.
Files are not sent to a server. Processing runs in your browser, and the queue handles one file at a time so the device stays responsive.

How to use it
Add images and choose 4, 8, 12 or a custom number of levels. The preview shows the first photo before the full queue is processed.
Recommended settings
4 levels creates a hard poster effect, 8 levels usually stays readable, and 12-16 levels gives lighter stylization with less detail loss.
Privacy

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