About Face Blur

Face Blur finds the faces in a photo and hides them for you, entirely in your browser — nothing is uploaded. It's the quick way to protect people's privacy before you share a picture online, post a crowd shot, publish a screenshot, or redact a document. Detection runs automatically, and because it isn't perfect you stay in charge: draw a box over anything it missed, or remove a box it added by mistake. Choose a soft blur, chunky pixelation, or a solid box for complete removal.

  • Use the solid box for true redaction of sensitive photos — it removes the pixels, not just softens them.
  • If a face is missed, switch on “Add box” and drag a rectangle over it.
  • Turn the strength up for smaller or lower-resolution faces.

Frequently Asked Questions

Are my photos uploaded anywhere?
No. The whole thing — finding faces and blurring them — happens right in your browser on your device. Your photo is never sent to a server.
What if it misses a face, or boxes something that isn't a face?
Automatic detection isn't perfect. You can draw a box over anything it missed, and remove any box it added by mistake — so you're always in full control of what gets hidden.
What's the difference between blur, pixelate and a solid box?
Blur softens the face so it's unrecognisable but still natural-looking. Pixelate replaces it with big blocks. Solid box covers it completely — the strongest option for true redaction.
Is blurring enough to truly anonymise someone?
A strong blur or pixelate makes a face very hard to recognise, but for sensitive documents the safest choice is the solid box, which removes the pixels entirely.
Which image formats work?
Common photo formats — JPG, PNG and WEBP. You can download the result as a PNG or JPG.
Why does the first run take a moment?
The face-finder gets ready the first time you use it, then it's quick. Everything stays on your device throughout.
