How to Convert M4B Format to MP3 and Stream Audiobooks Flawlessly

M4B is an audio file that stands for the MPEG-4 audio layer. One of its standout features that help audiobook listeners is its ability to remember the last listening spot. Instead of you starting all over again and finding the last listening spot, M4B did the job. Meanwhile, if you are an avid fan of reading and always purchase iTunes audiobooks, M4B is a great format. The problem is that the format does not allow playing audiobooks across all devices. It is selective with the media player or device for listening. One thing the listener can do is convert M4B into MP3. Stick out until the end to learn how to do this.

Part 1: Why You Should Convert M4B to MP3

Originally, M4B files were designed for audiobooks. This format is not universally accepted by media players and devices. Earlier, we told you that M4B audiobooks can be purchased on iTunes.

What it means is that it is limited to devices and media players where it can play.

If you are the type of user who likes simplicity, the general audio playback in MP3 will do the job. With these in mind, M4B to MP3 conversion is of main concern.
