Blur faces in a photo

Hide faces in photos before you share them. The AI finds the faces; you check them, add any it missed, and choose blur, pixels or a solid box. It runs in your browser, so your photos stay on your device.

How to blur faces in a photo

  1. Choose your photos, or drop them onto the page.
  2. Select Find faces to check the boxes: turn any off, or drag on the photo to add one. Pick blur, pixelate or a solid box.
  3. Select Blur faces and download your photos one by one or as a ZIP.

Questions

Are my photos uploaded anywhere?

No. The AI runs inside your browser on this device, so your photos are never sent to a server. That matters most for the photos you want to blur faces in.

Can the blur be undone?

No. Each face is first reduced to a few blocks of average colour, so the detail is gone from the saved file: there’s nothing for an “unblur” tool to recover. A solid box removes it completely. Your original photo isn’t changed.

Does it find every face?

It finds most faces turned towards the camera, down to about 10 pixels across in big group photos, and many side views and partly covered faces. Tiny, blurry, turned-away or heavily covered faces can be missed, so check each photo and drag a box over anything it missed. Boxes also hide name tags, number plates or screens.

Is the location and other hidden data removed?

Yes. The saved photos don’t include hidden metadata such as the GPS location, camera details or the date the photo was taken.

Which AI model does it use?

YuNet, a face detector by Shiqi Yu and colleagues from OpenCV Zoo, released under the MIT licence. Your browser downloads it from this site the first time, 0.2 MB, and keeps it.
