About the Video Watermark

Video Watermark stamps your logo or a line of text onto your footage so your brand travels with every repost. Drop in a transparent PNG logo or type a text mark, choose the corner, opacity and size, and burn it permanently into the video. It all runs locally in your browser with WebAssembly FFmpeg — nothing is uploaded, so even unreleased footage stays private.

    FFmpeg runs in your browser via WebAssembly, so your video is processed on your device and never sent to a server.

Video Watermark FAQ

Can I use a transparent PNG logo?
Yes — transparent PNGs work best because only the logo shows over your video. JPG and WebP also work if you don't need transparency.
Can I control how see-through the watermark is?
Yes. The opacity slider goes from a subtle faint mark to a fully solid stamp, with a live preview as you adjust.
Where can I place the watermark?
Any of the four corners or the center of the frame, with an automatic margin so it never touches the edge.
Is my video uploaded anywhere?
No. All processing happens locally in your browser with WebAssembly FFmpeg, so the file stays on your device.
What formats can I use?
MP4, MOV, WebM, MKV and M4V up to 1 GB. The result is an MP4 that plays everywhere.
