About this tool
Upload a photo to automatically detect faces and blur them, using the same on-device face-detection model as the Portrait Cropper — useful for anonymizing photos before sharing.
How to use
- Drop or select a photo.
- Detected faces are blurred automatically; toggle individual faces on or off.
- Download the blurred image.
FAQ
Can it miss faces?
Face detection isn't perfect — small, angled, or partially obscured faces may be missed. Always review the result before sharing.
Is the blur reversible?
No, the blur is applied destructively to the downloaded image, similar to how a real redaction should work.
