Is my video uploaded to a server?

No. The watermark is applied locally in your browser, so your video never leaves your device.

Can I add my own logo as a watermark?

Yes. You can overlay a logo image or use a text watermark, and adjust its position and opacity.

Which video formats are supported?

You can add a watermark to MP4 and WebM videos and export back to MP4 or WebM.

Does it cost anything?

No. The tool is free to use and runs entirely in your browser with no account required.

Will the watermark reduce my video quality?

The watermark is rendered onto the video during export. We aim to preserve the original quality as closely as the chosen output format allows.

Can I remove the watermark later?

No. Once a watermark is rendered into the exported video it becomes part of the frames, so keep your original file if you may need an unmarked version.

Do I need to install anything?

No installation is needed. Everything works in a modern web browser on your computer.
