Posting event photos, news images or pictures of children often means hiding faces — and painting over each one by hand is slow. This tool uses the YuNet face detector to find every face automatically, and scans large group photos in tiles so distant faces are caught too. Choose pixelate, blur, a black box or a smiley emoji, as an ellipse or rectangle, and widen the coverage to hide hair and ears as well. Raise the sensitivity to catch side and small faces, or lower it to avoid false hits. The model is only about 230KB and runs in your browser, so photos never leave your device. Any face that slips through can be covered manually with the Pixelate Image tool.

## How to use

1. Drop in one or more photos
2. Choose the effect, shape and coverage, and check the detected faces in the preview
3. Click Blur faces and download

## FAQ

### A face was missed — what now?

Raise the detection sensitivity first. Strong profiles, covered or very blurry faces may still be missed; cover those by hand with the Pixelate Image tool.

### Can pixelation be reversed?

Pixelation and blur are lossy, so the original face cannot be recovered from the exported image. For the safest result choose Black box.

### Is any face data stored?

No. Detection runs in your browser only to locate the areas to cover; there is no face recognition, and nothing is stored or uploaded.

### Are my files uploaded?

No. Everything runs locally in your browser with no network upload, and is discarded when you close the page.
