FAQ

Which Kindle formats?

MOBI (older), AZW (Kindle 2-3), AZW3/KFX (newer Kindle). The tool detects format from the file header.

What about DRM-protected books?

This tool only handles DRM-free files. Your purchased Kindle books are DRM-protected — removing DRM is legal for personal use in some jurisdictions; check local law.

Are images preserved?

Yes — embedded cover art and illustrations render in the output PDF.

How does formatting transfer?

Chapters, headings, bold/italic, lists. MOBI's reflowable layout becomes fixed pages. Page count varies with your chosen font size.
