Pull the audio out of your AVI file and save it as MP3, right in your browser.
Drag and drop the file, or click to browse. Files up to 500 MB are supported, and nothing is installed.
MP3 is already selected. Switch between MP3 and WAV if you change your mind.
We convert on our servers, usually in under a minute. Create a free account to download the MP3, or keep editing the file in REQO.
AVI is a Microsoft container from 1992. It still turns up in old archives, camcorder dumps and downloaded footage, but it predates modern compression and has no idea what a phone is.
The practical problem: Phones, browsers and social platforms do not play AVI at all. The legacy codecs inside waste enormous amounts of space compared with H.264. No support for modern features like proper streaming, chapters or clean seeking.
MP3 solves that. Plays on every phone, car stereo, browser and podcast host in existence. Small enough to attach to an email or send in a chat. Accepted by every transcription and podcast service.
| AVI | MP3 | |
|---|---|---|
| Container | Audio Video Interleave (Microsoft) | MPEG audio layer III |
| Typical codecs | DivX, Xvid, MJPEG and other legacy codecs | MP3 (lossy) |
| Best for | Opening archive footage from the 2000s | Podcasts, voice notes, music you need to send |
| Plays on | Desktop players with the right codec pack | Every device made in the last 25 years |
| File size | Very large for the quality | Roughly a tenth of uncompressed audio |
Yes. Convert and preview the result for free, then create a free account to download it. There is no per-file charge and no watermark on the MP3 itself beyond the free-plan badge.
No. The conversion runs on our servers and the whole flow happens in your browser, so it works the same on Windows, macOS, Linux, iPhone and Android.
The audio is decoded from the video and written as MP3. MP3 is a lossy format, so there is a small re-encode, inaudible for speech at the default quality. The picture is discarded entirely, which is why the file gets so much smaller.
Up to 500 MB per file. For anything bigger, trim or compress it first, both are free tools here.
Your upload is processed and then held only as long as your project needs it. Nothing is published, indexed or shared unless you create a share link yourself.
