About the formats
MP3, the audio that plays everywhere
MP3 compresses sound lossily, removing what the ear barely notices, so a song takes just a few megabytes.
Strengths: Any phone, car, speaker, player or program plays it, however old.
Limits: It loses some quality with each re-encode and, at the same size, sounds worse than AAC or Opus.

Frequently asked questions
Is my AVI uploaded to a server to turn it into MP3?
No. The AVI to MP3 conversion runs entirely in your browser, with code downloaded from this site and executed on your device. You can check it in the Network tab of the developer tools or by going offline after the page loads.
Can I extract only part of the AVI audio?
Yes: in the options set the start and end time, for example from 1:30 to 2:45, and only that clip is extracted.
Is there a size limit?
Up to 2 GB and 3 hours of video on desktop; on mobile, 500 MB and 30 minutes (AVI: 1 GB and 1 hour on desktop). If it is over, you are told before it starts and can trim it.
Can I convert several AVI files at once?
Yes. Drop as many AVI files as you like: several are converted at the same time, depending on your processor cores, and when they finish you can download each MP3 or all of them in a ZIP.
