The AVI format might be formidable, but if your goal is to turn your audio into video, it’s only natural to switch to the most popular format since most media players will support it, and that format is MP4. Alas, converting an audio file into a video isn’t easy. You’ll at least require the help of a powerful tool, but that’s not always the case.

Today, you’ll find out the best AVI to MP4 converters, including both third-party software and online converters. However, before that, it might be better to answer a very common question regarding this subject.

Part 1. Can Windows Media Player Convert AVI to MP4?

Windows Media Player is capable of converting from an audio format to another audio format, the same with videos, but it’s capable of switching from audio to video, or vice versa. So no, you can’t use Windows Media Player as an AVI to MP4 converter.

That’s precisely why we’ve mentioned earlier that you’ll need the help of a real converter since a simple media player won’t do. These converters may also apply compression when converting files. Speaking of which, is it possible to reduce file size through an AVI to MP4 converter?

Does Convert AVI to MP4 Reduce File Size?

Luckily, there are many converters out there that can automatically apply compression to converted files. What this means is that it will automatically reduce the file size of files, regardless of the original format and the output format.

However, that still depends on the AVI to MP4 converter. There are some with compression while others don’t. Only those with compression can be considered among the best AVI to MP4 converters, which leads us to the next question.
