All Ways to Convert M4B to MP3

M4B is a popular file extension that's generally used to store audiobooks. Even Apple uses M4B to keep audiobooks in iTunes. The major reason why M4B is a preferred choice for audiobooks is that it lets users store digital bookmarks. This means that whenever you play the audiobook on your iPhone/iPod/iPad, it'll automatically resume from where you left it off.

But, even M4B files have few drawbacks. For instance, these types of files can only be played on a few selected media players. In case you don't have a compatible media player/device, the only option to play an M4B audiobook would be to convert the file into MP3 first. Since MP3 is a widely used file type, it's supported by almost every media player.
