Frequently asked questions
How do I blur faces in a video for free?
Drop your video into the box above. Auto face blur is on, so every face it finds is blurred straight away in the preview. Check it, add a blur area for anything it missed, and download the MP4 — free, with no sign up and no watermark.
Does it blur faces automatically?
Yes. A face detector checks every frame and blurs each face it finds, following people as they move. It works best when faces are reasonably large in the frame; for small, distant or turned-away faces, add a blur area by hand and tick Follow.
How do I blur a licence plate, logo or screen in a video?
Click Add blur area and draw a box over it. If it moves, tick Follow and the box tracks it through the clip. Choose blur, pixelate or a solid black bar, and an oval or box shape.
Can I pixelate instead of blur?
Yes. Choose Pixelate for the classic mosaic look, Blur for a soft blur, or Black bar to cover the area completely. The Strength slider sets how strong the blur or how big the blocks are.
What if the blur slips off a moving object?
Follow tracks the area by matching what it looks like from frame to frame. Fast motion, the object turning or something passing in front can make it drift — draw the area a little bigger than the object, or add a second area from the moment it slips.
Is my video uploaded to a server?
No. Face detection, tracking and blurring all run in your browser and the MP4 is made on your device, so your video — and the people in it — never leave your computer or phone.
Does it keep the sound?
Yes. The original audio is copied into the new MP4 in sync. If your browser can’t encode audio, the tool says so and exports the video without sound.
How long can the video be?
Up to 60 seconds per export, at 720p or 1080p and 30 frames per second.
Does it work on iPhone and Android?
Yes, in the phone’s browser with no app. Phones default to 720p so the export is faster; keep the tab open while it renders.
Is a blurred face completely anonymous?
A strong blur, pixelation or black bar hides a face well, but always watch the result before sharing: check every frame where someone turns, is partly hidden or very small, and add an area anywhere a face shows.
