About the Blur Face in Photo

Blur Face finds the faces in a photo and covers them before you share it: blurred, pixelated or with a solid box. Detection runs on your device with YuNet, a small open-source face model from OpenCV, and large photos are also searched in overlapping tiles so the small faces at the back of a group are found too. You check the result, switch covers off, and drag over anything else that should be hidden, such as a number plate, a name badge or a screen.

Faces are found by YuNet, a small open-source model (227 KB) downloaded from Devtoolry once and run in your browser. The photo is never uploaded, and the download is a new image without the original's metadata.

How to use the Blur Face in Photo

  1. Choose a photo, drop it on the page or paste a screenshot with Ctrl+V.
  2. Wait a moment while the faces are found; each one gets a numbered box.
  3. Click a box (or use the list) to leave that face visible, and drag over the photo to cover anything that was missed.
  4. Pick Blur, Pixelate or Solid box, the strength and the shape, then download the photo.

Common mistakes

  • Trusting the detector blindly. No face detector finds every face. Look over the whole photo before sharing, including reflections, posters, phone screens and people in the background.
  • Forgetting what identifies people besides faces. Name badges, school uniforms, tattoos, house numbers, number plates and screens can identify people as surely as a face. Drag a box over them too.
  • A light blur on a large photo. At low strength a large face can stay recognisable. Raise the strength or use Pixelate or Solid box for photos that will be shared widely.

Frequently asked questions

Is my photo uploaded?

No. The face model is downloaded once (227 KB) and runs in your browser; the photo is never sent anywhere. You can check this in your browser's developer tools: the Network tab shows no request carrying the photo.

Can a blurred face be un-blurred?

Not here: every cover first shrinks the area to a handful of cells, which throws the detail away, and only then smooths or enlarges it. A light blur made with a plain blur filter can sometimes be partly reversed; for the strongest protection use a high strength or a solid box.

Why was a face missed?

Faces in profile, from behind, very small, covered by hands or masks, or in deep shadow are hard for any detector. Always look over the photo before you share it, and drag a box over anything the model missed.

Does it remove the location from the photo too?

Yes. The download is a new image drawn by your browser, so the GPS location, camera details and other metadata of the original are not carried over.

Does it work on phones?

Yes, in current Chrome, Safari, Firefox and Edge on Android and iPhone. Very large photos take longer on phones because more tiles are searched.

Can I blur a video?

Not yet: this tool works on still images (JPEG, PNG and WebP, and other formats your browser can open).
