Blur faces in video

Every face in a video found, followed as it moves, and blurred or pixelated. No upload, no account, no watermark: your video never leaves your device.

Free, no watermark, no account. Any size of video.

How to blur faces in a video

Four steps, with nothing to install and no account to make. It works in your browser, on a computer or a phone.

  1. Choose your video

    Drop a file on the page, or pick one from your phone's videos. MP4, MOV, WebM and MKV all work.

  2. Every face is found

    As soon as it's chosen, every face in it is found and followed as it moves, on your device. Each one gets its own cover, listed under the video.

  3. Choose how, and check

    Pixelate, blur, a block or an emoji, and how big. Play the video to check; remove any face you'd rather leave showing.

  4. Export

    It's made on your device as an MP4, at high quality, and saved with the original's name: party.mov becomes party_ohsovideo.mp4.

Questions about blurring faces

Is my video uploaded to blur the faces?

No. The faces are found by your own browser, on your device, and the new video is made there too. Nothing is uploaded, which is the point when the video is one you don't want to share as it is.

How does it find the faces?

With face detectors that run in your browser, looking at every frame. Each person gets one cover, which fits their face and stays on it when they move, turn away for a moment or the camera shakes; when the video cuts to another shot, the covers change on that very frame. Size makes the covers bigger.

Can I leave one face showing?

Yes. Every face found is listed under the video; remove the ones you want to leave showing, and only the rest are hidden.

Does it find small faces far off?

Usually. A face that looks small and unsure is looked at again, closer. A face only a few pixels across, far in the background, can be missed.

Blur or pixelate: which hides more?

Pixelate, which is the default. A light blur can sometimes be partly undone, but big squares can't. Block covers a face with a solid colour, and Emoji with a sticker.

Does the sound stay?

Yes. Only the picture changes. The sound is kept as it is.

Does it work on a phone?

Yes, in Safari on iPhone and Chrome on Android, though finding the faces takes longer on a phone. Long videos are quickest on a computer.
