Pixelation has two very different uses. Small blocks turn a photo into retro pixel art — the 8-bit look that suits game graphics, posters and playful posts. Large blocks hide information completely: a face, a number plate, a document detail, reduced to anonymous squares.

Drag the block-size slider and the preview updates live. Small blocks keep the photo recognisable with a retro feel; large blocks make details genuinely unreadable, which is the point when you are censoring. The download is a new file — your original is never touched.

To hide just one area instead of the whole photo, use the blur region tool — it blurs or pixelates only the rectangle you choose.

Frequently asked questions

What block size should I use?

4–8px for retro pixel art that stays recognisable. 24px or more to genuinely hide a face, plate or document detail.

Does pixelation really hide details?

At large block sizes, yes — the underlying pixels are averaged away in the download, so the detail cannot be recovered from the file.

Can I pixelate just one area?

Yes — the blur region tool pixelates or blurs only the rectangle you choose, leaving the rest sharp.

Is my photo uploaded?

No. Everything runs in your browser; your photo never leaves your device.
