Up to 2 GB. Long or high-resolution clips can run out of memory in your browser.

Final blurred video
The download is an H.264 MP4. Odd widths or heights are trimmed by one pixel because the format needs even numbers, and re-encoding can change quality. Watch the whole clip before you share it: a moving subject can leave a fixed area.
Runs entirely in your browser. Your video is never uploaded.
How to use

- Set the blur strength and process the whole clip.
- Review the exported video, then download the MP4.

FAQ
Will the blur follow a moving face?
No. Each rectangle stays in the same position for the entire clip. Check the full export because a moving subject may leave the blurred area.
Is my video uploaded?
No. Processing happens in your browser. Large clips may exceed your device's available memory even when they are below the file-size limit.
Does blur permanently protect private information?
Blur is a visual effect and is not a guarantee of secure redaction. Review the entire exported clip and use an opaque cover when details must be completely hidden.
