## Good to know

- Only the audio track is kept — the result is an AIFF file you can play anywhere. Use Options to pick a bitrate.
- Converting to AIFF won't restore detail that WebM compression already removed, but it prevents any further quality loss when you edit and re-save.
- This conversion runs on FFmpeg (WASM), running locally in your browser — nothing is uploaded and it works even on slow connections.
