Einschränkungen
AZW3 Einschränkungen
- Proprietary and DRM-locked to Amazon accounts.
- Requires Kindle hardware or the Kindle app to read "officially".
- No open specification — reverse-engineered by the Calibre project.
- Conversion to EPUB loses some Amazon-specific features (Whispersync, annotations).
- Ebook collectors prefer EPUB for archival because of DRM risk.
EPUB Einschränkungen
- Kindle does not support EPUB natively (Amazon wants you to convert to AZW3).
- Fixed-layout EPUBs (for children's books, comics) are awkward to author.
- Rendering quality varies between apps — some CSS works everywhere, some does not.
- Adobe DRM (ADEPT) or Apple FairPlay are optional layers that complicate portability.

EPUB is the open ebook standard — it plays on every e-reader except older Kindles and in every major ebook app. PDF is better for fixed-layout content (textbooks, coffee-table books) and printing. Pick EPUB when the ebook is reflowable text, PDF when the layout matters more than the reading experience.
