Pixelate or blur?
Pixelation (mosaic) replaces the face with large single-colour blocks. It reads clearly as intentional and looks good in editorial photos. Blur is softer and less distracting, which suits casual photos.
For privacy, block size matters more than the style name. Few, large blocks hide far more than many small ones.
Choosing the right strength
FaceHush offers five mosaic levels, from a fine 20-block grid across the face down to just 3 blocks. For anyone who could be at risk if identified, use the strongest level or a solid cover.
Questions
Is the pixelate tool free?
Yes. The web tool is free with no sign-up and no watermark.
Can pixelation be reversed?
A mosaic throws away detail, so it cannot be undone exactly. Research has shown that light pixelation can still let software match a face, so use large blocks or a solid cover for sensitive photos.
Does it work on group photos?
Yes. The tool scans the whole image in overlapping sections to find small faces. If one is missed, drag a box over it.
