What is M4B?

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 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 online digital content stores, such as iTunes.

However, since iTunes audiobooks are protected, 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 convert the protected M4B to MP3 format with some dedicated iTunes M4B audiobook converters. We will talk about this in the first part. On the other hand, many M4B files are not protected. For those M4B files, you can use many well-known tools like iTunes and VLC to convert M4B to MP3, which is introduced in the second part.
