Before you post a video filmed in public (a street, a school event, a shop, a protest), blurring the faces of people who didn’t agree to be in it protects their privacy, and in many countries it is a legal requirement for some uses.
When to blur
- Bystanders in vlogs and street footage.
- Children, unless parents agreed.
- Customers or staff in business videos.
- Witnesses or sources in news and documentaries.
Manual vs automatic
In a video editor you draw a blur mask and move it frame by frame (motion tracking helps). Fine for one face in a short clip, very slow for crowds.
Automatic face blur finds every face and follows it through the video. Our blur faces tool does this online: the AI finds and tracks faces frame by frame.
Check the result
- Watch the whole video: faces in profile, very small, or partly hidden can be missed for a few frames.
- Blur also what identifies people besides faces when needed: name tags, license plates, screens.
- Keep the original file private; share only the blurred one.
