A free, open-source Windows application that converts Audible's proprietary .aax (and older .aa) audiobook files to plain MP3 or M4A/M4B formats using FFmpeg. It preserves chapter metadata, supports splitting by chapter or track length, and runs conversions in parallel across CPU cores.

Use cases

  • convert audible aax audiobooks to mp3
  • convert aax to m4b with chapters
  • split audiobook into per-chapter files
  • remove drm from audible audiobooks
  • convert old .aa audible files
  • fix chapter marks in audiobook conversions
  • make long audiobooks itunes compatible

When to choose

  • you need to convert Audible .aax/.aa files to standard audio formats on Windows
  • you want chapter metadata preserved or chapter-based file splitting
  • you want a free open-source alternative with parallel conversion performance

When to avoid

  • you need conversion on macOS or Linux - this is a Windows-only application
  • you want a command-line or scripted batch tool rather than a GUI
  • you need to download books directly without Book Lib Connect, Audible Manager, or an activation code
