This article will explain what an M4A file is and how to open one on your computer. We will also look at how to convert an M4A file to another file format.

A file with the file extension M4A is an MPEG-4 audio file. They are most commonly found in Apple's iTunes Store as the format for song downloads.

Many M4A files are encoded with the lossy Advanced Audio Coding (AAC) codec to reduce file size. Some are lossless instead, using the Apple Lossless Audio Codec (ALAC).

When you download a song from the iTunes Store that is copy-protected, it is saved with the file extension M4P.
