About
TrackPeel started as a simple need: pull the audio out of a WebM or MKV recording as an MP3, without installing anything or uploading a file anywhere. Everything the tool does — the audio extraction and the MKV rebuild — runs inside your browser tab using FFmpeg compiled to WebAssembly. There's no upload step, because there's no server in the loop for the conversion itself.
Most online converters ask you to upload a file, wait in a queue, and download the result — which means your video sits on someone else's server, however briefly. Running the conversion client-side avoids that entirely, at the cost of a size ceiling imposed by browser memory limits (see How it works for the details).
A desktop companion app is in development for people who regularly work with files too large for a browser tab to handle — it'll use a native FFmpeg install instead of WebAssembly, removing that size ceiling. It'll be linked from the homepage once it's ready.
