Discussion: Convert AAX to MP3 Online VS on Desktop, 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. 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.

Part 2. What is the Best Converter for AAX to MP3?

After learning the above 4 AAX to MP3 converters in detail, it's time for you to choose the best one to convert your AAX files. In my opinion, not every AAX to MP3 converter can be regarded as the best. When one can both meet your basic needs perfectly and surprise you with some bonus features, they can be a good converter. Below are the features we reckon as the key elements and hidden features of the best AAX to MP3 converter.

Batch Conversion and Fast Speed

Most audiobooks are long audio that runs for hours. A good converter should convert AAX files at an extremely high speed. Moreover, the batch conversion feature is what makes an AAX to MP3 converter stand out. If one can batch convert audiobooks really fast, you can save much time.

Original Sound Quality and Flexible Parameter Setting

AAX files contain audible stories of high quality. No one would like it if the conversion loses the sound quality of the audiobooks. On the other hand, If the AAX to MP3 converter provides sample rate and bitrate settings, it will be more flexible in managing the file size and quality.

AAX Protection Removal

.aax to .mp3 is not just an extension conversion. Most AAX files are protected with DRM, only an excellent AAX to MP3 converter can bypass the protection and convert the audiobook to a DRM-free file.

ID3 Tag Preservation

Original AAX audiobooks are with ID3 tags, with which the player can read the information such as the title and the artist of the book. The best AAX to MP3 converter is supposed to keep them or even make them editable.

MP3 Audiobook Split by Length

If you don't finish the whole story at a time, then it will be best if the converter can split the audiobook into several clips by chapter or a customized length.
