One file at a time. The video is edited on your own device, so nothing is uploaded and there's no size limit beyond what your browser can hold.
How to blur a video
- Drop a video in the box above.
- Set how strong the blur should be and watch the preview.
- Download. The file keeps its name and its format, with -blurred added.
- The first video also fetches the video engine, about 7MB, which your browser then keeps. After that it starts straight away.
About blurring video here
This blurs the whole frame rather than a part of it. That's the right tool for a background behind other content, for a placeholder, or for making a clip unreadable before sharing it as an example of something.
It is not the tool for hiding one face or one number plate. Blurring only a region needs the picture cut out, blurred and laid back over the original, and a way to drag that region while it moves through the clip. That's a genuinely different job and this page doesn't pretend to do it.
This edit changes the picture, so every frame has to be decoded and encoded again. Your own machine does that work, which is what keeps the file off anybody's server, and it's why a long clip takes longer than a short one. Trimming and removing the sound are the two things here that skip it entirely.
Common questions
Is the blur a video free?
Yes, properly free. No paid tier, no trial, no watermark on the result and nothing to sign up for. Put as many files through it as you like, as often as you like.
Are my files uploaded to a server?
No. The blur a video runs inside your browser, on your own machine, so your files never go anywhere. Big ones are fine too, up to whatever your browser can hold.
Can I blur just one part of a video, like a face?
Not on this page, which blurs the whole frame. Covering one face or one number plate means cutting that region out, blurring it and laying it back over the picture, and following it as it moves. Cropping the clip so the thing you want hidden falls outside the frame is often a simpler answer, and it's completely reliable.
Is a blurred video safe to share?
Treat a strong blur as making something hard to read rather than impossible to recover. It genuinely destroys detail, and at a high strength there's nothing left to reconstruct. At a light setting, text and faces can sometimes still be made out, especially if the same content appears across many frames. Crop it out if it truly must not be seen.
