iTunes converts WAV to MP3 on Mac easily. There are just a few simple steps to follow. If you happen to have uninstalled iTunes before, it's time to reinstall it using the App Store or directly from the link below.
Download iTunes for Mac
Step 1. Open iTunes
The first step of converting WAV to MP3 on a Macintosh would be to open iTunes.
Step 2. Change the import settings
Move your cursor on top of the menu bar, click iTunes, and from the drop-down menu, click on Preferences.
To use a Mac to convert WAV to MP3, on the Preferences pop-up window:
For Import Using, choose MP3 Encoder.
Next, select a file quality type, such as Higher Quality (192 kbps).
Click OK when you are happy with your selection and go back to the main window.
Step 3. Find the song you want to import in the library
The iTunes library will automatically update all the songs it finds on the computer. If you have a large number of files, use the search function to find what you want.
Step 4. Convert it to MP3
You can right-click on a song title to access the Create MP3 Version option from the drop-down menu. If, for some reason, that option is not enabled when you right-click on a song's title, you can access it by going to File, then Convert, and then Create MP3 Version.
iTunes will go ahead and convert that file to MP3. When it's done, you'll have two versions displayed one after another. They may look the same, but you can right-click on the file and select Get Info to view the file format of each.
Want to burn that MP3 file to a CD? Here are the simple steps to do so:
First, create a new playlist.
Add any MP3 you want into the new playlist by drag-and-drop.
Right-click on your playlist and select Burn Playlist to Disc.
When the pop-up menu appears, make sure to select Audio CD.
Your MP3 CD will be ready in a few minutes! This is how you convert WAV to MP3 on a Mac.
