Blur Faces in Video, FreeHide a face, a passer-by or a screen before you post.

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.

Drop a video to blur faces

An MP4, MOV, WebM or MKV clip. Faces are found automatically; you choose who stays visible.

Or paste a video. Clips up to 10 minutes.

Private by design: faces are found on your device and your video is never uploaded.

THREE SIMPLE STEPS

How to blur faces in a video

Add your video

Choose, drop or paste an MP4, MOV, WebM or MKV clip up to 10 minutes long. Faces are looked for right away; the first time, the small face finder downloads once.

Choose what to hide

Untick anyone who should stay visible, draw a rectangle or ellipse over anything else and set when it starts and ends. Scrub through the preview to check every part of the clip.

Export

Pick blur, pixelate or a solid fill, then export. Every frame is redrawn with the areas hidden and saved as an MP4 with the original sound.

BEFORE YOU POST

Hide what should not be in your clip

Nothing is uploaded

The face finder runs in your browser and the video is decoded, blurred and saved on your device. Only the face finder's model file is downloaded, once.

Check the preview

Automatic finding can miss a face that is turned away, very small, covered or in the dark. Scrub through the clip and draw an area over anyone it missed.

Not only faces

Name tags, house numbers, street signs, number plates, screens and documents can identify people too. Draw an area over them for the time they are visible.

Moving objects

Turn on keyframes for an area, then move it at a few points of the clip: in between, it travels in a straight line from one position to the next.

Use enough strength

A strong blur or large pixels make a face hard to recognise. For sensitive footage, a solid fill hides the most.

A safety margin

When the finder loses a face for a moment, the last box stays hidden a little longer and grows slightly, so a face does not flash into view between frames.

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.
