Blur Faces in Video Online

How to blur a moving face

1. Select a local clip. Trim longer videos first to fit the 60-second limit.
2. Detect and select faces. Keep the tracks you want covered enabled. Draw manual masks without detection if needed.
3. Check the coverage over time. Pause, scrub and use the frame-step controls around entrances, turns and exits. Move or resize the rectangle to correct its position; inspect the frames between corrections.
4. Set effect and audio. Choose blur, mosaic or solid black. Adjust strength and padding, then check Keep audio.
5. Export, review and download. Keep the tab open. Review the complete result, then download. Corrections clear the old result, so export again after changes.

Example: a visitor crosses behind a presenter

Leave the presenter’s tracks unchecked and cover the visitor’s. If the visitor passes behind a pillar and returns, the return may be a new track. Check both sides of the obstruction and add a manual rectangle where detection misses. End that mask when the visitor leaves so it does not cover an unrelated area later.

Cover the right part of the image

Leave enough padding for head turns and changing face size. One manual position does not track motion automatically; add and review later positions. Undo and redo let you compare corrections.

For background softening while keeping people visible, use video background removal. To discard only sound, remove the audio track. If you compress the result, review that final version too. Browse all free tools.
