# AVI to MP3

This converter saves the sound from an AVI video as an MP3 on your own device. AVI is common in older camera and archive footage. Only the audio is decoded, so the video codec does not matter. We test AVI files with MP3 audio; other sound codecs may work. Nothing is uploaded. The first run downloads a 32 MB engine.

Runs on your device

## How it works

1. Choose your AVI file.
2. Pick a bitrate. A lower one makes a smaller file.
3. Press convert to MP3.
4. Download the MP3.

## Key facts

- **Tested with**: AVI with MPEG-4 video and MP3 audio.
- **Video codec**: The picture is not decoded, so the video codec does not affect the conversion.
- **If it fails**: You get a plain message rather than an empty file.

## Common uses

- Saving family camcorder sound before the old file is lost.
- Getting the audio from an archived talk.
- Cutting an old video library down to just the speech.

## Questions

### My AVI has audio in an unusual format. Will it work?

It may. We only promise what we tested, which is MP3 inside AVI. If the engine cannot read it, the tool says so and nothing is lost.

### Can I fix quiet audio too?

Yes, as a second step. The increase volume tool accepts AVI, and the MP3 made here.
