Face Blur
This free face blur tool finds every face in a photo with on-device AI and hides it — blur it, pixelate it, or cover it with a solid block. Detection and editing run entirely in your browser, so the image never leaves your device.
Runs entirely in your browser — the image never leaves your device. Detection is automatic; for privacy-critical images, prefer Solid (blur/pixelate can be partly reversed). The first run downloads a small model, then it's cached.
How to use Face Blur
- 1 Drop an image onto the box, click to browse, or paste one with Ctrl/Cmd+V.
- 2 Pick an effect: Blur, Pixelate, or Solid (a solid block can't be reversed).
- 3 The tool detects faces automatically and shows how many it hid.
- 4 Download the PNG, copy it, or open it in the annotator for further edits.
Frequently asked questions
Is my image uploaded to detect faces?
No. Face detection uses an on-device AI model that runs in your browser, so the image and the result never leave your device.
Which effect is safest for privacy?
Use Solid. Blur and pixelate can sometimes be partly reversed, but a solid block permanently removes the face pixels.
Why is the first run slower?
The first time you use it, the tool downloads a small face-detection model. After that it's cached, so later runs start much faster.
What if no faces are detected?
You'll see a note that none were found. Try a clearer, better-lit image where faces are larger and facing the camera.
