Face Blur — Blur Faces in Photos Automatically
Automatically detect and blur or pixelate faces in photos, right in your browser. Toggle individual faces, add missed ones and download — no uploads.
🔒 Runs entirely in your browser — nothing is uploadedAnonymise faces before you share a photo
Street scenes, event pictures, classroom photos and screenshots of video calls often show people who never agreed to be published. Blurring their faces protects their privacy and helps you meet rules such as the GDPR or school and workplace policies. Doing this by hand is slow, so this face blur tool finds faces automatically and hides them in one step. You stay in control: every detected face gets a box you can switch on or off, so you can keep the main subject visible while bystanders are anonymised, and you can drag extra boxes over faces the detector missed, such as profiles or people wearing masks.
Detection uses Google's MediaPipe face detector running in your browser with WebAssembly. On first use, the small face detection model is downloaded once from Google's public model storage and the detection engine is loaded from this site; your browser can cache both for later visits. The photo itself is processed only on your device and is never uploaded, which matters when the whole point is privacy.
Blur or pixelate, and how strong?
Both effects work by shrinking each face region to a handful of samples and enlarging it again, which permanently discards facial detail rather than just softening it. Blur gives a smooth, natural look; pixelate produces the familiar mosaic blocks. Raise the strength until the face can no longer be recognised — for real anonymisation use at least the middle of the slider. The oval shape follows the face more naturally, while the rectangle also covers hair and ears.
Getting reliable detection
The standard mode is fast and works best for close-up and medium shots. Group photo mode additionally scans overlapping sections of the image so that small faces in crowds or wide shots are found too. If a face is still missed, lower the sensitivity slider and detect again, or simply draw a box around it. Always check the result before publishing: no automatic detector is perfect with extreme angles, heavy shadows or very tiny faces. The saved file contains no boxes and no original EXIF metadata such as GPS location.
