Quick answer: To extract MP3 audio from AVI video, add the AVI file to the iHateFiles AVI to MP3 converter and press Convert. The conversion runs in your browser, so the file is never uploaded, and it is free with no sign-up, watermark or size limit. Lifts the soundtrack out of the video and saves it as MP3. The picture is discarded; nothing is re-recorded.
Should you convert AVI to MP3?
Worth doing when you want the soundtrack of a AVI on its own: a podcast, an interview, a piece of music from a video. Choose a higher bitrate than you think you need, because the MP3 is encoded from the video's audio rather than from a master.
Taking the sound out of AVI
A AVI file holds a picture track and a sound track side by side. This keeps the sound and discards the picture, so what you get is the MP3 on its own at whatever bitrate you choose. Nothing about the AVI original is altered.

What usually goes wrong
About the AVI. Audio drifting out of sync partway through an AVI is common, because the container assumes a fixed frame rate that the source did not actually have. Re-encoding to MP4 corrects the timing.
About the MP3. Converting an MP3 to another lossy format compounds the damage, because the second encoder is guessing at audio the first one already threw away.
How to convert AVI to MP3
- Add your AVI file. It is read from your disk and stays there.
- Check the settings. The output format is already set to MP3.
- Press convert and the MP3 file is saved back to your device.
Questions
How do I convert AVI to MP3?
Open this page, add your AVI file, and press convert. The file is decoded and re-encoded by your own browser and saved back to your device. Nothing is uploaded.
Is this AVI to MP3 converter free?
Yes, completely. There is no account, no sign-in, no watermark and no daily limit, because there is no server doing the work. Your own device does it.
Are my files uploaded anywhere?
No. There is no upload endpoint. The conversion runs inside this browser tab, so your file never leaves your device. You can open your browser's network panel and watch: nothing carrying your file is sent.
Is there a file size limit?
No fixed limit. Because the work happens on your machine there is no server quota. The only ceiling is your own device's memory, which for video means very large files may be slow.
Does extracting audio reduce the quality?
The soundtrack is re-encoded to MP3, so there is one generation of loss at the bitrate you choose. Pick a higher bitrate, or a lossless target like WAV or FLAC, to avoid it.
Can I convert several AVI files at once?
Yes. Add as many as you like and they are converted one after another, then offered as a single ZIP.
