This article explains what M4B files are, how to open them on your device, and what programs you need to convert them to another format, such as MP3, FLAC, WAV, etc.

A file with the file extension M4B is an MPEG-4 Audiobook File. They are often used by iTunes to store audiobooks.

Some media players use the M4B format to store digital bookmarks along with the audio, allowing you to pause playback and resume later. This is one reason they are preferred over MP3s, which can't save your place in the file.

The M4A audio format is essentially identical to M4B, except that those file types are used for music instead of audiobooks. Apple's iPhone also uses the MPEG-4 audio format for ringtones, but those files are saved with the M4R extension instead.
