Blur Faces in Video, Free
Faces are found automatically and followed from frame to frame, so each person gets their own box. Tick who to blur and who to keep. Draw extra areas over a name tag, a street sign or a screen, set when they start and end, and export an MP4 with the original sound.

Blur faces in video FAQ
How do I blur faces in a video for free?
Open your clip on this page. Faces are found and followed automatically; untick anyone who should stay visible, add areas for anything else, pick blur, pixelate or a solid fill and export. There is no sign-up and no watermark.
Is my video uploaded?
No. Everything happens in your browser: the video is read, blurred and saved on your device. The first time, the browser downloads the face finder (about 3 MB) and keeps it for next time.
Does it find every face?
Not always. Faces are looked for several times a second and followed in between, but a face seen from the side, very small, covered, blurred by motion or in the dark can be missed. Always scrub through the preview before posting and draw an area over anything that is still visible.
Can I keep my own face and blur everyone else?
Yes. Each person found gets a number and a picture in the list. Untick the people who should stay visible; everyone else is hidden.
Can I blur a sign, a screen or a moving object?
Yes. Add a rectangle or an ellipse, place it on the frame and set when it starts and ends. For something that moves, turn on keyframes and move the area at a few points of the clip.
Is the sound kept? What do I get?
Yes, the original sound is kept. You get an MP4 at the size and length of your clip (WebM in a browser that cannot save MP4). Clips can be up to 10 minutes; every frame is processed on your device, so longer clips take longer.
