Pixelate part of an image

Drag a box over what you want mosaicked — the preview shows the real block size before you commit. One click can also auto-detect and pixelate every face in the photo, on-device.

Because nothing is uploaded, this is a genuinely private way to censor screenshots and photos before sharing them.

Censor with a live preview

Drag a box over whatever should be mosaicked — a face, a plate, a screen — and the preview shows the real block size before you commit. One click can also auto-detect and pixelate every face in the photo, on-device. Because nothing uploads, this is a genuinely private way to censor screenshots and photos.

A note on security: pixelation obscures but can occasionally be partially reversed on simple content. For information that must be unrecoverable, use Redact, which destroys the pixels entirely.

How it works

  1. Drop an image and open Pixelate.
  2. Drag a box over the area (or hit auto-detect faces).
  3. Apply — repeat for more areas — then download.

Like every pixelpix tool, this runs 100% in your browser: your file is never uploaded to a server, never leaves your device, and works even offline once the page has loaded.

Frequently asked questions

Is pixelation reversible?
It is much harder to reverse than blur, but for truly sensitive data use Redact, which replaces the pixels with a solid block so nothing can be recovered.
Can it pixelate faces automatically?
Yes — an on-device face detector can find and pixelate every face in one undoable action.
Can I pixelate several areas?
Yes, apply it region by region; each is its own undoable edit.
