Video WatermarkNEW
Overlay a text or image watermark on a video and export it
Checking your access…
AllFreeTool is a free online video watermarking tool that burns a watermark into a clip. You can use a text watermark, which supports Chinese, English and common symbols, or upload your own transparent image, then choose the position, the size, the opacity and the margin. The result is exported as a new video file, processed locally in your browser with no upload.
It suits branding a tutorial or a social clip, marking a proof-of-concept video so nobody reuses it, or protecting a recording you are sharing with a client. The watermark is composited into the picture rather than laid over it in a player, so it cannot be switched off by whoever plays the file.
Why use Video Watermark on AllFreeTool?
Text or Image
Burn in a text watermark or your own transparent PNG or WebP logo.
Five Positions
Place the watermark in any corner or in the centre of the frame.
Size and Opacity
Scale the watermark, set its transparency and control the margin from the edge.
Local Processing
The overlay is composited in your browser, so the video is never uploaded.

Common questions
How does the watermark get into the video?＋
The browser draws the watermark onto a transparent canvas, which is then composited over the video frames with an overlay filter. Because the result is baked into the exported picture, it cannot be removed by playing the file in another program.
What image format works best for a logo?＋
A transparent PNG or WebP gives the cleanest result, since any background in the image is burned into the frame along with the logo. A solid background will appear as a visible box around your watermark, so remove it before uploading.
Can I control how prominent the watermark is?＋
Yes. The opacity setting fades the watermark, the size control scales it, and the margin sets how far it sits from the frame edge as a percentage of the video width. A small, low opacity corner mark works well for branding, while a large centred one is stronger for a proof of ownership.
Is the video uploaded to a server?＋
No. The video is read and re-encoded in your browser with no network request for the media. Your clip and your watermark image stay on your own machine, and nothing is stored once the page is closed.
