How to Add a Watermark to Video Online
Drop your video above, add a text or image watermark, and adjust the position, size, and opacity to your liking. Hit export to get a watermarked MP4. The watermark is burned into the video frames, so it cannot be removed by a viewer. No upload. No account.
Watermarking is essential for protecting preview cuts sent to clients, branding social media content, and marking draft versions. Text watermarks work best for copyright notices. Image watermarks are better for logos. If you need to trim the video first, use the video trimmer.
Burned-In Watermarks vs Overlay Watermarks
A burned-in watermark is permanently encoded into the video pixels. It survives re-encoding, screen recording, and format conversion. An overlay watermark, by contrast, is a separate layer that some players display on top of the video. Overlays can be stripped out by anyone with basic tools.
This tool creates burned-in watermarks. Each frame is decoded, composited with your watermark via canvas, and re-encoded as H.264. The result is a standard MP4 where the watermark is part of the image data. This is the only reliable method for protecting video content.
Why Watermark Video in the Browser?
Uploading sensitive pre-release footage to a cloud watermarking service defeats the purpose of protecting your content. This tool processes everything on your device. Your video and watermark assets stay local throughout the entire workflow.
After watermarking, you can compress the output or convert it to WebM for web embedding. For professional burned-in caption workflows, explore Velocaption. Browse all free tools on the tools page.
