Video Watermark Blur
Cover watermarks, logos, timestamps or private details in any video with adjustable blur boxes. Upload a video, drag the boxes into place, preview the blur live, then export the finished video — all in your browser.
1. Upload your video
Supported: MP4, WebM and other browser-playable formats. The file never leaves your device.
How to use
- Choose a video file from your device.
- Press Add Blur Box and drag the box over the watermark, logo or detail you want to hide.
- Adjust blur strength and box size with the sliders.
- Press Play Preview to see the blur in action on the video.
- Press Export Blurred Video, then download the result.
Note: Export re-renders the whole video, so a long video can take a while. The exported video keeps the original resolution.
Tips
- Make the box a little larger than the watermark so edges stay covered when the video moves.
- Use stronger blur for text watermarks and lighter blur for corner logos.
- You can stack several boxes to cover multiple areas in one export.
- Export once and check the downloaded file before deleting the original.
