How to Perform WAV-to-MP4 Conversion

Edited by Pat Bitton

August 30, 2019

WAV is an older format, introduced in 1991. It is used to store non-compressed audio files and is in wide use among Windows users because the format was developed by Microsoft. Since WAV files commonly contain audio with no compression, they are usually large. And WAV files can’t be played on some devices that don’t support this format.

So, it would be useful to be able to change the .wav file extension to something more usable, for example, .mp4. This is a media container that can store not only video but also audio, and MP4 is much more popular among device manufacturers than WAV. A good WAV-to-MP4 converter will easily transform your files. Below, you will find a guide to how to convert WAV to MP4 with Movavi software, plus a short WAV vs. MP4 comparison.
