How to use the Face Blur

  1. Drop one or more photos.
  2. Faces are detected and covered in the chosen style; tick “Find small faces” for group shots.
  3. Click a box to keep that face visible; drag on empty space to add a box, for example over a number plate.
  4. Download single images or a ZIP. Exports have EXIF location data removed.

Mosaic, blur or solid block?

Mosaic and blur look natural, but weak settings can leave faces recognisable or partly recoverable by software. When privacy really matters, such as minors, witnesses or victims, choose the solid block, which keeps no original pixels. Emoji covers suit casual social sharing.

Why was a face missed?

The BlazeFace detector is best at frontal and slightly turned faces. Tiny faces, strong profiles, the back of a head or faces mostly hidden by masks or hats can be missed. For group photos tick “Find small faces” to scan the image in tiles, add any missing boxes by dragging, and zoom in to check before publishing.

Location data in photos

Phone photos often carry GPS location, device model and time in EXIF metadata. This tool re-encodes images on export, so none of that metadata is kept, which is a good clean-up step before posting.

Legal and etiquette notes

In many places, publishing identifiable photos of other people requires their consent, especially for children. Blurring is a good privacy habit but does not replace consent. For journalism, law enforcement or evidence, follow the relevant standards and keep the original files.

Frequently asked questions

Are my photos uploaded?

No. The face detection model (about 0.2 MB) downloads from this site and runs in your browser; photos are processed only on your device.

Can it blur videos?

Images only for now. Take screenshots of the frames you need and process those.

Can it detect number plates or text?

Automatic detection is for faces only. Drag boxes by hand over number plates, house numbers or shipping labels.

How do I keep my own face visible?

Click that face’s box; it turns dashed to show it is kept. Click again to cover it.

Does quality drop?

Exports keep the original resolution: JPEG sources export as high-quality JPEG and PNGs as PNG.

Can pixelation be reversed?

Light mosaic and blur can sometimes be recognised or partly reconstructed. Use the solid block for sensitive cases.
