Many people prefer using Audible for audiobooks. But do you know that you can also get audiobooks on iTunes? And the price for the same audiobook on iTunes seems to be lower than Audible. However, just like audiobooks on Audible, iTunes audiobooks are DRM-protected as well. And Apple uses its proprietary M4B container format to store audiobook files.


For Apple fans, this won't cause many hassles because protected M4B files are naturally compatible with Apple devices. But since you've been here, you may consider giving up on Apple devices. Then it is necessary to convert M4B to MP3. Otherwise, you may be at risk of losing access to your purchased iTunes audiobooks. No worry. Here provides 5 helpful methods to effectively convert M4B audiobooks to MP3. After converting to MP3, your M4B audiobooks will be playable on any device.

Part 1. The Easiest Method to Convert M4B to MP3 in Batch (Recommended!)

Before we show you how to convert M4B to MP3, it is better to know more details on the M4B audiobook format so that you can adjust the encoding settings much wisely.


What is M4B format?

A file with the M4B file extension is a MPEG-4 Audio Book file. The .M4B extension is specially designed for labeling audiobooks purchased from Apple's iTunes Store. And it is almost identical to the M4A extension because both these formats use the MPEG-4 Part 14 container format (commonly known as MP4). The difference is that the M4B format has a bookmarking feature which makes it convenient to find the exact point you were listening to.


When it comes to audio compression, the audio in an M4B file is encoded with the AAC compression format. Also, much similar to other media contents purchased from iTunes, the M4B audiobooks are protected with Apple's FairPlay DRM copy protection system. Therefore, if you want to convert DRM-protected M4B audiobooks, remind to find a converter that is capable of removing iTunes audiobook DRM as well as converting M4B to MP3.
