How to convert AVI to MP3

Upload your AVI file above.
Keep MP3 selected as the output.
Choose Balanced quality unless your workflow needs another setting.
Open Advanced settings only if you need trimming, resolution, bitrate, sample rate or a custom filename.
Start the conversion and download the finished file when it is ready.

Before you convert

AVI is usually less efficient and less web-friendly than modern MP4 or WebM workflows. Repeated lossy conversion cannot restore detail removed from the original source.

Changing a container or codec cannot recreate quality already missing from the source, so keep an important original when possible.
