About
Blur part of a video online, free. Drag a box over a face, a number plate, a name tag or a screen, and the tool blurs it, pixelates it or covers it with a black box in every frame. It runs in your browser, so the video is not uploaded.
Add as many boxes as you need. Each one can stay for the whole video, or only from one moment to another: pause where it should start and click Start here, then where it should end and click End here. The preview shows the boxes as you play, so you can check them before you export.
Boxes stay where you draw them; they don't follow a moving subject. For something that moves, draw one box over its whole path, or several shorter boxes one after another. The sound is kept, and nothing is added to the video.

Questions
Is blurring a video free?
Yes. It is free, needs no account and adds no watermark.
Is my video uploaded?
No. The blurring happens on your device and nothing is uploaded.
Can I blur more than one thing?
Yes. Draw as many boxes as you need, each with its own start and end time.
Does the blur follow a moving face?
No. Each box stays where you put it. Cover the path of a moving subject with a larger box or several timed boxes.
Which hides best: blur, pixelate or black box?
A black box hides completely. Strong blur and pixelate hide detail while keeping the scene readable; raise the strength for small text.
