Updated on April 28, 2024

Q: I recently downloaded a copy of an Audible book in AAXC format on my Android device. To ensure easy access to any audio player, I’m looking for a solution to convert AAXC to MP3 that is compatible with more devices. Is there a way to do this?

Actually, you may have noticed that the books saved by the Audible app for Android or iOS use the AAXC format. But what exactly is Audible AAXC and why is Audible using this new format? Is it possible to download an Audible AAXC file to MP3 for backup or playback on devices that don’t support Audible? In this article, we will tell you the best answer to convert AAXC to MP3 for PC, Mac, online and for free.

Part 1. What Is an AAXC File

AAXC is a file extension designed to provide stronger copyright protection for Audible audiobooks. It has been available to Audible books since June 2019, which can only be played in the Audible app for Android or iOS.

Specifically, the audiobooks downloaded from the Audible mobile app will be saved in the new AAXC format instead of AAX. Also, AAXC is an updated version of AAX but its encryption scheme differs from AAX, which means it is more difficult to move the downloaded Audible books to non-Audible devices.

🔔Note: The Audible books downloaded from the computer are still stored in AAX.

Part 2. Why Convert AAXC to MP3

📌AAX vs AAXC vs MP3

AAX is a DRM-protected M4B container with AAC sound, which is widely used for Audible audiobooks on Windows and Mac. The bitrate for it is 32-128kb/s.

AAXC is almost identical to AAX but with a newer and better DRM system, which is used for Audible books downloaded through the Audible mobile app.

MP3 is a widely used and non-DRM audio format known for its compact file size, good sound quality, and compatibility with various devices.
