Desktop and Online AAX to MP3 Converter: Which is Better

1. Desktop VS Online: DRM Removal

Desktop converters can convert both DRM-protected and unprotected AAX audiobooks, while online converters can only convert DRM-free ones. If most of your Audible books are encrypted with DRM, desktop converters are better.

2. Desktop VS Online: Efficiency and Flexibility

Desktop AAX to MP3 converters are often more efficient and flexible due to hardware acceleration and batch conversion. Also, they can cut audiobooks by time, chapter, or segment. All the features may be inaccessible on online converters.

3. Desktop VS Online: File Size

Most online AAX to MP3 converters limit file size. For example, you can only upload less than 100MB AAX files to AnyConv and less than 40MB unencrypted Audible to Aconvert. Whereas there is no size limitation for MuConvert Audible Converter to convert AAX to MP3.

4. Desktop VS Online: Free Service

Free online AAX to MP3 converters are slow. Desktop versions often start free but may introduce paid features later. Neither option is ideal in this regard. However, the regular updates, customer support, batch download, and more features of desktop AAX converters still make them worth the price.

The better AAX to MP3 converter depends on your needs and priorities. If you want a more reliable and professional AAX to MP3 audiobook converter, it is advisable to choose desktop software, like MuConvert Audible Converter, which can support you with a ton of great features.
