Which videos can I extract audio from?

This tool accepts video files supported by the bundled ffmpeg build. The file never leaves your device, so there is no upload limit — the only ceiling is what your browser can hold in memory.

Does the tool keep the video’s original audio codec?

No. It removes the video stream and re-encodes the audio with the MP3 encoder at FFmpeg quality level 2.

What if the video has no audio track?

FFmpeg cannot create a meaningful MP3 without an audio stream, so processing reports an error.

Can I choose a specific audio track?

No. The interface has no track selector and relies on FFmpeg’s default stream selection.
