Waveform Audio File Format simply known as WAV is a high-quality lossless audio format originally created to be used for uncompressed audios on Microsoft Windows systems. It is an accurate, lossless format i.e. it can reproduce the recordings without losing any data or quality. Although it can be a bit large compared to mp3, sometimes we just need high-quality audio. Mp3 is a compressed version of WAV, WAV is so high quality that the difference in both may not be noticeable or may come out as background noises unless with the use of a high-quality speaker. In the process of compressing a WAV file into Mp3, it sheds some data and its quality drops making it playable on regular PC/Smartphone speakers or headsets.

There are tons of audio file converters that can convert not only audios but videos as well. Compared to other process of compressing, audio compression is relatively easy and simple but only with the use of good converters.

Is Wav better than Mp3?

This question is subjective, an MP3 is a lossy file format meaning when being converted it loses some data, therefore, the quality will drop but so will the media file size, while WAV is a lossless file format and that means it retains all its data from the original recording, therefore, its quality is top-notch. So, it depends, in terms of audio quality WAV wins hands down and in terms of space management MP3 all the way.
