Convert AVI to MP3.
Pull the soundtrack out of an AVI video as an MP3 that plays on any phone, car stereo or computer.
Old videos, portable sound
AVI was the standard for camcorder exports, old downloads and early screen recordings. When it is the sound you want, such as a concert, a talk or a family recording, an MP3 is far easier to keep and play.
Quality
The MP3 is encoded at 128 kbps. Old AVI soundtracks are often MP3 already, so the result sounds the same for everyday listening.
Size change
At 128 kbps the MP3 takes about 1 MB a minute, far smaller than the AVI.

Common questions
Is it free?+
Yes. Convert AVI to MP3 free. No signup and no watermark. Free covers 10 server conversions a day, up to 100 MB a file. Pro removes the daily limit and raises the file limit to 2 GB.
Is my file private?+
Your file is uploaded to a private bucket, converted on our own engine, and auto-deleted after 1 hour. It is never sent to a third-party converter.
What happens to surround sound?+
MP3 holds mono or stereo only, so a surround track is mixed down to stereo. For every channel, extract to WAV instead.
Is the video kept?+
No. Only the audio goes into the MP3, and your AVI is not changed. To keep the picture in a modern format, use AVI to MP4.
