What is Video Watermark?

Video Watermark stamps a text label — your name, a brand, a handle, or a copyright notice — permanently into every frame of a video, in one of five corner or center positions. It accepts MP4, MKV, AVI, MOV, and WebM as input and always saves the result as an MP4.

Unlike a watermark added in a video player's overlay (which anyone can strip out by re-recording or editing), this one is burned directly into the pixel data by FFmpeg's drawtext filter, the same way captions get permanently burned into a video. That makes it genuinely part of the footage rather than a removable layer, which matters for protecting ownership of a clip shared publicly or distributed outside your control.

The whole process runs inside your browser via FFmpeg WebAssembly, so your clip is never uploaded anywhere.

Need a watermark on a document instead of a video? Watermark PDF stamps text or an image across PDF pages.

How It Works

A text file containing your watermark message is written to FFmpeg's in-memory filesystem, along with a TTF font loaded once from a CDN. FFmpeg's drawtext filter then renders that text onto every frame at the chosen position with a semi-transparent background box for legibility, and the result is re-encoded as H.264 video with AAC audio.
