M4B is similar to M4A. It is a file extension for audiobooks or podcast files. The main difference between M4B and M4A is that M4B files support metadata for chapters and bookmarking while M4A doesn't.
Due to M4B files are rarely supported by portable players other than the device from Apple, many people want to convert M4B to MP3 or M4A. However, M4B to MP3 conversion process maybe not as simple as you think.
When it comes to converting M4B to MP3, many people may recommend using iTunes to convert M4B to MP3. Not surprisingly, perhaps, you will be failed. That’s possible because the M4B audiobooks you want to convert are copyright-protected by digital rights management software (DRMS).
Many M4B audiobooks are available on the internet for free, but more can be purchased in online stores like iTunes. If the M4B audiobooks are purchased from the iTunes Store, they are protected. In this case, you cannot use the common converter or iTunes to convert them to MP3 format. In other words, you need a professional M4B to MP3 Converter.
