How to Convert MP3 to WAV and Vice Versa

Edited by Pat Bitton

December 3, 2019

WAVE (Waveform Audio File Format), better known as WAV and also called Audio for Windows, is a standard format used by Microsoft for saving and playing digital audio under Windows. This format is compatible with RIFF containers and is closely related to the 8SVX and AIFF formats used by Amiga and Macintosh computers. Formerly, it was a basic format for Windows and uncompressed audio. Uncompressed audio files have good sound quality but can be very large, and not all the media players, mobile phones, or other mobile devices can play files in this format. If you want to save space on your hard disk or listen to your favorite music on your iPod or Mac, it’s better to convert WAV files to the MP3 format.

This article describes 3 ways to convert WAV to MP3 or vice versa. You’ll also learn about the differences between the two formats in our comparison table.

In the Output format field, set MP3 or WAV, depending on your needs – you can turn WAV into MP3 just as easily as MP3 into WAV. You will find the MP3 presets under Audio > MP3. Here, you can choose the preset with your preferred bitrate, but remember that the higher the bitrate, the greater the quality and file size will be.

WAV vs. MP3 Сomparison

MP3 vs. WAV: what’s the difference? The WAV file format can contain audio encoded with different codecs. It is mostly used to store uncompressed audio, that’s why WAV files are often quite large. MP3 is the name for both the audio codec and the container format. The MP3 codec is used for lossy audio compression, so MP3 files are relatively small. This format is very popular and can be played on almost any device.
