MP3 and WAV are two of the most popular audio formats worldwide. They both have unique advantages and drawbacks, making each ideal for very different contexts. For this reason, you may wish to convert MP3 files to WAV on Mac or Windows PC, depending on the changing context. However, converting audio files from MP3 to WAV format isn't always simple. You need to use the right tool to perform the conversion. Otherwise, quality issues, conversion problems, and playback issues may occur. Therefore, we've created this detailed guide for Mac users to convert audio from MP3 to WAV format.
Part 1. Why Change MP3 to WAV on Mac?

MP3 is the mainstay of several industries that deal in audio content. The lightweight audio format is universally compatible thanks to its low file size and great quality-to-size ratio. MP3 files compress and purge large chunks of crucial audio data in favor of file size. So, the audio quality is much lower when compared to an uncompressed audio format. For casual applications and users, MP3 makes perfect sense as an audio format.
On the other hand, WAV has a more niche fan following. Unlike MP3, WAV is an uncompressed audio format. The audio data is stored in its original quality without any compression. Therefore, the WAV files are significantly larger than MP3 files.
However, the purpose behind MP3 to WAV conversion isn't quality. Since MP3 files are compressed, resulting in data loss, converting them into WAV will not restore lost data. What's lost is permanently lost. So, the most common reason behind MP3 to WAV conversion is compatibility. Some audio editors, for instance, handle uncompressed WAV audio better than compressed MP3 audio.

A1. Yes. iTunes is the built-in tool that supports batch conversion of MP3 files to WAV format on Mac. For a more robust tool with advanced file conversion features, choose HitPaw Univd. It lets you customize the output quality, size, and other customizations too.
Q2. Will converting MP3 to WAV preserve metadata like artist and title?
A2. That depends on the tool you use. For instance, a tool like HitPaw Univd gives you control over whether you'd like to preserve, edit, or delete metadata during MP3 to WAV conversion. However, some tools, such as FFmpeg are known to strip audio files of their metadata during conversion.

A3. As long as you own the MP3 files you're converting, it's perfectly legal to do it for personal purposes. However, if you're converting files that you do not own, then legal complications may arise. Also, if you're converting copyright-protected MP3 files for distribution, that would be illegal in many jurisdictions.
