Anonymity without losing the testimony
Sometimes the value of an interview is in what's said, not who said it. A source speaking on condition of anonymity, a whistleblower raising concerns, or a research participant sharing a sensitive experience may need their identity protected before footage is shown to others or published.
Blurring the face is a recognised way to do this while preserving the human qualities that make an interview compelling — the cadence of speech, gestures, and body language. AnonymizeVideo.app keeps the audio and the rest of the frame intact so the testimony still lands, just without revealing who is on camera.
Trusted with sensitive footage
🔒 Never uploaded
Interview footage is processed entirely in your browser. Nothing is sent to a server, so a sensitive recording stays under your control.
🗣️ Speech stays intact
Original audio can be preserved, so the words, tone and pacing of the interview are kept exactly as recorded.
🚶 Body language preserved
Only the face is obscured — gestures and posture remain visible, keeping the interview natural and watchable.
🎯 Stays redacted
Sticky tracking keeps the face blurred as the subject turns, leans or moves, so identity isn't accidentally revealed between frames.
How it works
Three steps, all in your browser — no software to install.

Frequently asked questions
Is the interview uploaded to be processed?
No. Everything happens locally in your browser. The recording is never sent to a server, which matters when you've promised a source anonymity.
Does the audio stay the same?
Yes. Original audio can be preserved, so the spoken testimony is unchanged while the face is blurred.
Will the blur slip if they move?
Sticky tracking follows the face as the subject turns or shifts, and you can review the result and re-run if needed before exporting.
Can I use a stronger redaction than blur?
Yes. As well as blur you can apply pixelation or a solid block for a more complete obscuring of the subject's identity.
