When it comes to audiobooks, the universal format used by many audiobook converters is MP3; however, when it comes to Apple devices, the format is M4B. This format contains almost everything you might need, such as chapter markers, hyperlinks, and even cover images. Another advantage of the M4B format is it is bookmarkable. This means that you can bookmark a chapter or page and return to it whenever you resume playing.

But if you convert MP3 to an audiobook, then there are two ways to go about it. For those who want to convert MP3 to an audiobook with chapters, you have come to the right place. This article will help you understand those two ways, and you can pick one method at your convenience.

Part 1. How to Make an Audiobook from MP3 through iTunes

If you have the iTunes app on your computer that runs Windows OS or macOS 10.14 Mojave (or earlier), you can finish this work easily. Since the iTunes is the alternative to the Music app and share the same functionality, you'll go through a very similar process in the Music app to make your MP3 files to audiobooks.

To add mp3 file to iTunes:

For starters, please make sure the mp3 file is imported to iTunes already. Or you can add the file or folder that contains all mp3 files to iTunes from there.

1. Open iTunes.

2. From the top menu select File > Add File to Library or Add Folder to Library.

3. Navigate to find all the mp3 files or folder that contains them in Windows Explorer or Finder. Select the item and open it.

4. Now the mp3 file is under the Recently Added tab under Library in the side menu (at this time the Apple Music Contents menu is selected as Music.)

To make an audiobook from mp3 file in iTunes:

Please follow these steps to change the genre and media kind of the iTunes MP3 files.

2. Locate and select the mp3 file from iTunes.

How to Convert MP3 to an Audiobook (M4B) through iTunes

You can take advantage of iTunes to convert your MP3 audiobook file to AAC.

To convert MP3 to AAC in iTunes:

1. Select the mp3 file under the Audiobooks section.

2. Choose File from the top menu > Convert > Create AAC version. Now iTunes will start converting and it will be done within seconds.

3. Head to the Recently Added tab under Library in the side menu.

4. Drag and drop the item to your desktop and you see the file extension is .m4a.

However, this is not the perfect solution since the file format is not changed and matched with any audiobook players that support M4A, M4B and more. Or if you want the M4B - the audiobook file format that will make more sense, head to the Part 2 to meet 2 options, and both of them have more supported output formats.

Part 3. How to Convert MP3 to an Audiobook (M4B) with ViWizard

M4B - The audiobook file format

As LABS mentions, a file with an M4B extension, is an AAC encoded, MPEG-4 audio file, usually used within the Apple ecosystem to bundle audiobooks files. In addition to storing audio content, M4B file format also supports digital bookmarking (so that you can resume listening from the point you left off last time), and chapters markers (a feature similar to that found in DVDs).
