Before You Convert: What Are M4A And MP3?

Before choosing a converter, it helps to understand what M4A and MP3 actually are, what sets them apart, and how we test the tools to convert M4A to MP3 format.

What is M4A?

M4A (MPEG-4 Audio) is an audio format developed by Apple and commonly used in iTunes or Apple devices. Most M4A files use AAC (Advanced Audio Coding) to keep file sizes small while maintaining high sound quality. Some M4A files use ALAC (Apple Lossless Audio Codec) instead, which preserves the original audio quality but results in a larger file size.

What is MP3?

MP3 (MPEG-1 Audio Layer III) is the most common audio format. It works on almost everything and is easy to share. The file size is smaller, but the quality can be a little lower.

Take a look at the key differences between M4A and MP3, so you know which one makes more sense for your situation.

Now that we understand the formats, we tried each converter the same way to see how well they perform. Here are the things we looked at:
