TrackPeel

Runs on your machine, not our servers

Pull the audio.
Keep the video.

Load one or more WebM/MKV files, hit convert, and download the MP3 and rebuilt MKV for each. Everything happens locally in your browser tab — nothing is uploaded.

Working on it

🖥️ A desktop app for larger files is on the way — it won't have this limit, since it runs a real converter on your machine instead of inside the browser. It'll be linked here as a free download once it's ready.

How a conversion runs

01

Load

Your file is read only inside this tab. Nothing is uploaded anywhere — the "server" for this step is your own CPU.

02

Extract

FFmpeg (compiled to WebAssembly) demuxes the Opus track and re-encodes it as MP3.

03

Rebuild

The original video stream is copied — not re-encoded — into a fresh MKV alongside the new MP3 track. Download either file when it's done.
