What Is M4B & Why Convert M4B to MP3

Before we get into the solutions to convert M4B files to MP3, let's firstly take a look at the M4B file itself.

M4B is a file extension for audiobooks based on the MPEG-4 Part 14 standard. Unlike M4A, another common audiobook format, the M4B audiobooks support chapter markers which make it easy for listeners to jump to the beginning of any chapter while playing. Currently, most M4B audiobooks are sold from the online digital content stores, such as iTunes.

However, since iTunes audiobooks are protected by Apple's FairPlay DRM, you can only play those M4B files on authorized computers and Apple devices. In order to play iTunes M4B on common MP3 players or other devices, you'll have to remove DRM from the M4B books and convert the protected M4B to MP3 format with some dedicated iTunes M4B audiobook converters.
