How to convert a video to MP3
- Choose a video file from your device.
- Pick an MP3 quality. 192 kbps suits music, and 96–128 kbps is plenty for speech.
- Press Convert to MP3 and download the audio.
The first time you use this tool, your browser downloads the media engine (about 31 MB, FFmpeg compiled to WebAssembly). It’s cached afterwards, so later uses start quickly. A computer is much faster than a phone for long files.
Only use videos you have the right to use
This tool works with video files on your own device, like recordings you made or files you’re allowed to use. It doesn’t download anything from YouTube or other sites.
Frequently asked questions

MP4, MOV, WebM, MKV, AVI, 3GP and most other common formats.
How long does it take?
Usually faster than the video’s length on a computer, because only the audio is processed.
