M4B is not as common as M4A though they both are MPEG-4 file types. If you like reading and always purchase audiobooks from Apple’s iTunes Store, you’ll find it frequently since it features that it allows listeners to remember the last listening spot instead of repeating the files from the start, whereas M4A extension files cannot. This is always considered as its advantage when we play it on authorized computers or Apple devices. But given that you want to listen to the M4B audiobooks anywhere and you don’t have a compatible multimedia player, converting M4B to MP3 is one of the ways-out since MP3 is the most popular audio format. Read along to know the best converters that you can rely on.

Further Reading: Differences between M4B and M4A

As what we have revealed at the very beginning, M4B is less known to people than M4A. When we buy audio files from iTunes Store, we find most of them are saved in M4A format and audiobooks are in M4B. Actually they are both a part of MPEG-4 format used for storing compressed audio/video. M4B is encoded in AAC coding only while M4A is in AAC, or Apple Lossless Audio Codec. Therefore, M4B is not as widely supported as M4A.
