What you get
The audio track is converted to a 192 kbps MP3 with ffmpeg running in your browser. It takes seconds for typical clips; the video itself is not changed.
How it works
Hybrid renderer: WebGL2 for color grading and effects, WebCodecs for decode/encode, ffmpeg.wasm for muxing and exotic codecs. Multi-threaded via SharedArrayBuffer where COOP/COEP is available. The processing code runs inside the page, so your file is not uploaded to a server — you can confirm this in your browser's DevTools → Network tab.
