How It Works

100% Private, your files never leave your browser. The video is composited 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. It masks your speaker clip into a circular bubble and overlays it on your background, in the corner and size you choose, 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 composite or generate videos automatically at scale? The Bannerbear API automates it for you. Plug it into your app or no‑code workflow and produce thousands of videos on autopilot.
