What is M4A?

M4A is a file that uses MPEG-4 codec to contain audio data. It is a popular audio format used to store digital audio files, particularly those purchased from online music stores like iTunes.

Is M4A Different from MP3?

As audio containers, M4A files are similar to MP3 files in terms of audio quality. However, they differ in some aspects.

An M4A file uses MPEG-4 codec, but it typically has better compression. M4A files can be played on a variety of devices and media players, including smartphones, tablets, computers, and portable music players.


MP3 is a more universal audio format, which is much smaller in size due to its adoption of MPEG-3 codec. It can be easily opened on Windows, Mac, smartphones, and other devices.

Why Change M4A to MP3?

MP3 files are usually more compatible than M4A files. If you are not only going to play and store M4A files on Apple devices, it is better to transform them into MP3 in order to enjoy your music on more devices.
