M4A audio can be played on Mac, iOS, Windows and other major platforms, but it is not universally supported by all devices and media players like MP3 format. This tutorial will show you 5 easy ways to convert M4A to MP3 on Mac with or without Macintosh built-in Apps. You can convert multiple M4A files to MP3 in seconds with lossless quality.  

 

M4A vs. MP3

M4A is an audio-only MPEG-4 file that is typically encoded with AAC (Advanced Audio Coding) or ALAC (Apple Lossless Audio Codec). It’s primarily used by Apple to distinguish it from the MPEG-4 video file with .mp4 extension, and it’s the default format for downloading songs from Apple’s iTunes Store.

MP3 is a popular audio format, compatible with almost all devices and players. Both M4A and MP3 are lossy audio formats and are compressed to reduce the file size for faster downloading and streaming.

So why convert M4A to MP3? The main reason is compatibility. Although M4A can maintain a good quality with a comparatively smaller size, it’s not widely supported by all devices, software and platforms like MP3 format. In this case, you can easily convert M4A to MP3 on Mac following this guide.
