How to use it

Add images and choose the pixel block size. The first file shows the effect immediately, and the queue processes the rest locally.

Recommended settings

8-12 px gives a soft pixel effect, 18-24 px hides details more clearly, and 32 px or more is better for strong anonymization or stylized covers.

Privacy

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

Limits

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