Things to Know Before Converting M4B to MP3

What is a M4B file? It is a MPEG-4 audiobook file containing audio data, metadata and encoding specifications that make it possible for users to bookmark a specific section of the audio data. M4A is very similar to M4B, but doesn’t allow users to bookmark. M4B files are encoded exclusively with AAC encoding.

iTunes and Apple devices have made this format popular. You can buy and download M4B audiobooks from the iTunes Store. A protected M4B file uses FairPlay encryption, a DRM technology developed by Apple, and can only play on authorized devices and computers. To listen to your M4B audiobooks on regular devices and portable music players, you can convert M4B to MP3 or other more popular audio formats. It’s also possible to use recording software to record an audiobook as MP3. When it comes to the DRM protected ones, we need to remove DRM before converting.
