How It Works

100% Private, your video never leaves your browser. The watermark is applied locally on your device using WebAssembly. Nothing is uploaded to our servers.

This tool runs FFmpeg, the industry‑standard video toolkit, compiled to WebAssembly so it runs entirely inside your browser. Pick a video and a transparent PNG or GIF, choose a corner and how long it shows, and it burns the watermark in, no account, no sign up, no server queue.

The first time you use it, the tool downloads the video engine (~30MB) to your browser and caches it, so later runs start instantly. Because the work happens on your own device, very large files may take longer on lower‑powered machines.

Want to watermark videos automatically at scale? The Bannerbear API automates it for you. Plug it into your app or no‑code workflow and watermark thousands of videos on autopilot.
