MP3 and AVI explained
What is a MP3 file?
MP3 is the most popular audio format in the world. Its lossy compression produces small files that play on virtually any device, which made it the standard for music and podcasts.
What is a AVI file?
AVI is a classic video container developed by Microsoft. It is widely compatible with older players but produces larger files, so converting to MP4 is often preferred.

Because the conversion runs on your own device, it also works offline once the page has loaded, and you can convert as many files as you want.
