Frequently Asked Questions

Can I pixelate only part of the image?

Currently the effect applies to the whole image. For selective pixelation, we recommend cropping the area first, pixelating it, then compositing. Selective pixelation is planned for a future update.

What pixel size should I use for censoring?

For effective censoring of faces or text, use a pixel size of 15-30px. Below 10px, details may still be recognizable.
