Limitations
EPUB Limitations
- 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.
PAGES Limitations
- Apple-only — Windows and Linux users cannot open .pages files.
- Binary IWA format is opaque — no third-party tooling.
- Track changes and collaboration features lag Word and Google Docs.
- DOCX round-trips lose some Apple-specific styling.
- Macro support is minimal (no VBA equivalent).
