Remove Video Watermark

Remove a static watermark or logo from your own video

Old camcorder footage with a burned-in date, a screen recording with a “trial version” stamp, your own channel logo on a clip you want to reuse, a TV-style corner bug on a video you made for a client — this tool helps you remove a watermark from a video you own. Draw a box over the mark once and every frame is filled in from the pixels just around it.

Two fill methods are offered. Inpaint uses the Telea algorithm from OpenCV (Apache-2.0), compiled to WebAssembly, and suits textured backgrounds. Fast fill works like the classic “delogo” filter: each pixel inside the box is interpolated from the edges, which is very quick and clean on smooth backgrounds such as sky or walls. Decoding and encoding use Mediabunny (MPL-2.0) and your browser’s built-in WebCodecs, so the video never leaves your device.

How to use the Remove Video Watermark

1. Drop your video on the upload area. Its duration, resolution, frame rate, codecs and size are shown.
2. Drag on the preview to draw a box just around the watermark. Draw another box for each extra mark; drag a box to move it or its round handle to resize it.
3. Pick Inpaint or Fast fill, and raise “Expand boxes” if a faint outline of the mark remains. Use the compare slider and the preview slider to check different moments.
4. Press Remove watermark. The progress bar shows the frame count, speed and time left; Cancel stops at any point.
5. Play the result with the Before/After buttons, tick “This is my video or I have permission to edit it”, and press Download video.

How the fill works — and why it has limits

Neither method knows what was hidden under the watermark; both rebuild the box from what surrounds it. Fast fill takes thin strips just outside each side of the box and blends them inwards, weighting each side by how close it is, so a gradient flows smoothly across. Telea’s fast-marching method (Alexandru Telea, 2004) fills the box from its border towards the centre, giving each new pixel a weighted average of nearby known pixels along the direction of edges; “Fill radius” sets how far it looks.

Both work frame by frame on a box that stays in one place. That makes them a good fit for a static logo or timestamp over a fairly calm background, and a poor fit for watermarks that move, fade in and out or change size, which are not tracked. Large boxes, or boxes over faces, text, fences and other detailed patterns, come out as a soft, smudged patch that can shimmer as the scene moves. Generative AI tools redraw such areas, but they are a different technology and are not used here.

Tips for a cleaner result

• Keep the box tight but cover the whole mark, including its shadow or glow; “Expand boxes” adds a few pixels all round.
• Try both methods on a busy and a calm part of the video using the preview slider before processing.
• If the mark sits in a corner, cropping it away often looks better than any fill.
• To hide something rather than reconstruct it — a face, a number plate — use Blur Video or Face Blur Video instead.
• For photos and screenshots, the same idea is available with a brush in Remove Image Watermark.

Copyright: only edit videos you are allowed to edit

Watermarks usually identify who owns a video. Removing one from a video you do not own, or from stock, broadcast or licensed footage you have not paid to use without it, can infringe copyright, and in several countries — including the USA (DMCA section 1202), the UK and India — knowingly removing copyright management information such as an owner’s name or logo can be unlawful in itself. Use this tool for your own recordings, footage you have written permission to edit, and harmless marks such as camera date stamps. The download stays disabled until you confirm that the video is yours or that you have permission. To protect your own clips, add a mark with the video watermark tool.
