Q: Is my video uploaded to a server?

No. The video is read into the browser's memory and processed with FFmpeg.wasm on your device. Nothing is uploaded.

Q: Why does the first run download about 32 MB?

The FFmpeg WebAssembly engine is loaded once and then cached by your browser and by this server, so later runs are much faster.
