Does it track faces as they move through the frame?

Yes, detection runs across the video, tracking and blurring faces as they move rather than blurring a single fixed region.

Will it catch every face, even at an angle or partially obscured?

Detection works best on clearly visible, front-facing or near-front-facing faces — partial profiles, heavy obstruction, or very small/distant faces in the frame are more likely to be missed.

Can I review the video before finalizing to check nothing was missed?

Yes, and it's worth reviewing the full output for privacy-sensitive footage specifically, since automated detection isn't guaranteed to catch every face in every frame.

Does Face Blur for Video upload my files to a server?

No. Face Blur for Video runs entirely in your browser using on-device processing, your files never leave your device.

About this tool

Protecting people's identity in footage — bystanders in street video, unconsenting participants in a recording, sensitive documentary subjects — traditionally meant manually tracking and blurring each face frame by frame, an enormously tedious process for anything longer than a few seconds. This tool automatically detects and blurs faces throughout a video, applying the blur consistently across every frame without manual frame-by-frame tracking.
