Online vs. Desktop AAX to MP3 Converters: Which is Better?

In this article, there are both desktop and online AAX to MP3 converters available for you to select from. But actually, there are big differences between using these two kinds of converters to convert AAX to MP3. The biggest difference is that only desktop AAX to MP3 converters, like TuneFab Audible Converter, can convert DRM-protected Audible files to MP3, while online converters can only convert DRM-free AAX to MP3.

Moreover, if you convert AAX to MP3 online, you need to make sure the files you upload are less than the preset file size limit. For example, you can only upload less than 50MB AAX files to Online Audio Converter. But you don't need to worry about the size limitation for you to upload your audiobooks to the desktop converters. Better yet, when you have a large-sized audiobook file, the desktop converters can help you split the files by duration, chapter, or segments.

After the above description, I think it's quite easy for you to choose whether to convert AAX to MP3 online or on a desktop.

What if the AAX to MP3 Converter Asks for an Activation Byte Code?

When you try to use an AAX to MP3 converter to convert your purchased and downloaded AAX file to MP3, the converter may ask for your personal Activation Byte Code. This is annoying. But don't worry, you have two solutions:

Option 1. Visit AAX Checksum Resolver, and drag and drop your downloaded .aax file to the website. It will analyze and generate the activation bytes.

Option 2. Download your audiobooks with Book Lib Connect. Books downloaded with Book Lib Connect do not need a classic activation code. You can use any of the best AAX to MP3 converters mentioned before to change AAX to MP3.
