Short answer
The audio track of a video file can be extracted to MP3 directly in a web browser. The video stream is discarded and the audio is re-encoded with the LAME MP3 encoder at a chosen bitrate, commonly 192 kbps. The conversion runs locally, so the video is never uploaded and there is no length limit.

Extracting audio is useful for lecture recordings, interviews, podcast episodes published as video, and music you already own on video. Because only the audio is kept, the resulting file is typically 1–3% of the original size.
192 kbps is the sensible default: it is transparent for speech and close to transparent for music. Use 320 kbps when the source is high quality music you intend to keep, and 128 kbps for voice-only recordings where file size matters more than fidelity.

Frequently asked questions
Does extracting audio lose quality?
Slightly. The audio is re-encoded from the video's original codec into MP3, which is lossy. At 192 kbps or above the difference is inaudible to most listeners on most equipment.
How long can the video be?
There is no imposed limit. A one-hour recording converts fine on a normal laptop. Very long files use more memory, so close other tabs if the page becomes unresponsive.
Can I extract audio from a YouTube link?
No. This tool works on files you already have on your device. Downloading content from streaming platforms may breach their terms of service and is not supported here.
Can I get a WAV or M4A file instead?
This tool outputs MP3, which is the most widely compatible option. MP3 plays on every phone, car stereo, browser and media player without additional codecs.
