Best Tools to Convert AVI to MP3 2023

AVI (Audio-Video Interleaved) is a container format that holds audio and video data. It's a format developed by Microsoft and as such is playable in Windows systems by default whether computers or mobile devices.

Although AVI promises high-quality audio and video, there are two drawbacks to the format.

Firstly, AVI has a large file size. This makes its sharing a little cumbersome. It explains why more often than not, AVI is converted to other mainstream formats to reduce file size without any noticeable quality loss.

The other disadvantage is it's not playable in certain media players by default.

If so, you would need an AVI to MP3 converter.

One program you could confidently choose for the purpose is DVDFab Video Converter.
