Frequently Asked Questions

Find Quick Answers

What is an AAX file?

AAX is Audible's proprietary audiobook format used for DRM-protected audiobooks purchased from Audible.com. It contains both the audio content and digital rights management information.

Is this conversion legal?

This tool is intended for personal use to convert legally purchased Audible audiobooks for personal listening on devices that don't support AAX format. Please ensure you only convert content you have the right to use.

What MP3 quality settings should I choose?

For audiobooks, 128 kbps bitrate and 44.1 kHz sample rate provide good quality with reasonable file size. Higher bitrates (192-320 kbps) offer better quality but larger file sizes.

How long does conversion take?

Conversion time depends on file size and server load. A typical 10-hour audiobook takes 2-5 minutes. The tool will show progress during conversion.

Are my files secure?

Uploaded files are processed securely and automatically deleted from our servers after conversion. We don't store or share your files.
