Frequently asked questions
- Is this really private?
- Yes. The extraction runs on your device via WebAssembly (ffmpeg compiled to run in the browser). Your video never leaves your computer.
- What audio quality do I get?
- The audio stream is re-encoded at high bitrate by default. Premium unlocks full bitrate/codec control.
- Which videos can I pull audio from?
- Anything the bundled decoder recognizes, which covers ordinary MP4 recordings, screen captures and camera clips. Copy protected files stay locked, here as everywhere else.
