Pixelate or blur — which hides a face better?

Both are destructive in Blurify's export, so neither can simply be 'un-filtered'. Pixelation reads as deliberate censorship and leaves nothing smooth to squint at; gaussian blur looks softer in casual photos. Pick by tone — or by how much you want the censorship to be seen.

Can pixelation be reversed?

Honest answer: coarse pixelation of a small region has occasionally been reconstructed in research settings, especially with tiny block counts over text. For faces, use a generous block size — or use the Solid fill style, which replaces the region entirely and leaves nothing to reconstruct.

Does it work on group photos?

Yes — every detected face becomes its own region, and you toggle each one individually. Pixelate the strangers, keep your friends.

What block size should I use?

The default is chosen so a face at typical photo size becomes 8–12 blocks across — unrecognizable but obviously censored. Drag the slider and watch the live preview; if you can still read an expression, go bigger.

Is pixelation the same as a mosaic effect?

Yes — 'mosaic', 'mosaic censor' and 'pixelation' all name the same block-averaging effect. Bigger blocks mean a coarser mosaic and stronger censoring; the slider covers the whole range.

How it works for pixelate.

Drop the photo
JPEG, PNG, WebP, HEIC/HEIF — up to 20 MB. Faces are auto-detected the moment the upload lands.
Switch the style to Pixelate
Every detected face starts as a region on the canvas. Pick Pixelate in the style control and set the block size — bigger blocks, stronger censoring.
Export the flattened copy
The blocks are baked into the exported pixels — not an overlay, not a filter. EXIF and GPS metadata are stripped on the way out.
