What M4B Files are and how they work

Audiobooks are typically stored in audio files with the M4B audio codec. It is comparable to an MP3 file, but it was created especially for audiobooks and has several extra characteristics.

What is an M4B file

The fact that M4B files permit bookmarking is one of the primary distinctions between M4B files and MP3 files. This implies that you can pick up where you left off if you put an audiobook down and return to it later. Additionally, M4B files frequently contain metadata that makes it simpler to browse through the audiobook, such as the title, author, and chapter information.


Digital audiobooks that are purchased or downloaded from online retailers like Apple Books or Audible frequently have the M4B file extension. Computers, smartphones, and specialized audiobook players are just a few of the devices that can play them. A media player that supports the M4B format, such as Apple’s iTunes or the VLC media player, is required to play an M4B file.

Podcasts or Lectures

M4B files can be used to store spoken-word audio in addition to audiobooks, including podcasts and lectures. Since they are made to retain lengthier audio content and offer more capabilities, they are often larger in size than MP3 files.

Audiobooks can be stored and listened to using M4B files, which offer a smooth listening experience and make it simple to browse through lengthy audio content.

Which is better: M4B or MP3 File Format

Both M4B and MP3 are popular audio file formats for storing and playing music and other audio recordings. Although they may initially appear to be comparable, there are some significant differences between M4B and MP3 that make one a superior option in some circumstances. In order to help you decide which is the better choice for you, we will compare M4B and MP3 in terms of their file sizes, compatibility, and quality in this post.

File size

The size of the files that are produced by M4B and MP3 is one of their primary differences. Due to the fact that M4B files employ a more effective method of audio compression, they are often larger than MP3 files. As a result, M4B files can conserve more storage space on your hard drive or other storage device while maintaining a greater degree of quality. Conversely, MP3 files are typically lower in size because they employ a less effective method of audio compression that reduces quality in order to conserve storage.

MP3 might be a better option if you are very concerned about file size. M4B might be the better option, though, if you’re ready to give up a little bit of extra storage space for audio of greater quality.


Compatibility is a key factor to keep in mind while deciding between MP3 and M4B. Audiobooks and other lengthy audio recordings are frequently stored as M4B files, which are largely connected to Apple’s iTunes and iPod products. They might not be as widely supported by other hardware and software because of this.


However, MP3 files are considerably more widely compatible and may be used with a variety of hardware and software, including computers, cellphones, tablets, and many other kinds of audio players. MP3 can be a better option if you want to guarantee that your audio files will work with a variety of devices.


The audio quality of M4B and MP3 is comparatively similar. Because both formats employ lossy audio compression, some of the original audio data is lost during encoding. However, due to its more effective method of compression, M4B files typically maintain more of the original audio quality. M4B files thus might sound a little bit better than MP3 files, particularly when played through high-end speakers or headphones.

However, most listeners frequently cannot tell the difference in quality between M4B and MP3, especially when the files are played on subpar speakers or headphones. The average audio quality difference between M4B and MP3 is negligible, and it’s possible that the larger file size of M4B files is not justified.

Frequently Asked Questions

Here are some queries our customers who utilize our online conversion service have sent to us.

Will converting the audio format affect its quality?

In general, converting an audio file from one format to another can potentially affect the quality of the audio. This is because the process of encoding and decoding audio involves some loss of information.

However, the extent to which the quality is affected can vary depending on a number of factors, such as the bit rate of the original audio file, the specific audio codecs used for the conversion, and the overall complexity of the audio content. In some cases, the quality of the converted audio may be indistinguishable from the original, while in other cases there may be some noticeable degradation in quality.

One way to minimize the potential impact on quality when converting audio formats is to use a higher bit rate for the original audio file, as this can provide more information for the conversion process to work with. Additionally, using a lossless audio format (such as WAV or FLAC) as the intermediate format during the conversion process can help preserve the quality of the original audio.

In general, it’s always a good idea to keep a copy of the original audio file in case you need to go back to it, as the quality of the converted file may not be as good as the original.

Can iPhone read M4B?

Yes, iPhones can play M4B files. M4B is a file format for audio books that is similar to the MP3 format, but it includes metadata that allows the audio book to be bookmarkable. This means that when you pause the audio book and then return to it later, the playback will resume from the point where you left off. To play an M4B file on an iPhone, you can use the built-in Apple Books app or a third-party app that supports the M4B format, such as Audible or OverDrive.

To play an M4B file using the Apple Books app:

  • Open the Apple Books app on your iPhone.
  • Tap the “Library” tab at the bottom of the screen.
  • Tap the “Audiobooks” tab at the top of the screen.
  • Tap the M4B file that you want to play.
  • The audio book will begin playing from the beginning. To pause or resume playback, tap the “Play” button at the bottom of the screen. To skip to a specific chapter or section, tap the “Table of Contents” button at the top of the screen and select the chapter or section that you want to listen to.

Note that M4B files are often DRM-protected, which means that they can only be played on authorized devices using authorized software. If you have an M4B file that is protected by DRM and you are having trouble playing it on your iPhone, you may need to use a different app or device to access the file.

What is the difference between M4B and M4A files?

M4B is an audio file format specifically used for audiobooks, while M4A is a general audio file format that can be used for music or other types of audio. M4B files often have chapters and bookmarks, which make them well-suited for listening to audiobooks. M4A files, on the other hand, do not have these features.

Why would I want to convert an M4B file to M4A?
