EPUB 3 adds support for multimedia, scripting, and advanced accessibility features including text-to-speech and screen reader compatibility.
Advantages
- Open standard supported by virtually all non-Kindle e-readers and reading apps

- Supports multimedia, interactivity, and comprehensive accessibility features
Limitations
- Not natively supported by Amazon Kindle devices without conversion
- Rendering varies significantly between different reading applications

Common Uses
- E-book distribution through Apple Books, Kobo, and Google Play Books

Target Format
HTML E-Book

Advantages
- Viewable in any web browser without specialized e-book software
- Full formatting capabilities with CSS styling and embedded images
- Natural input and output format for e-book conversion tools
Limitations
- No e-book-specific features like bookmarks, annotations, or offline library management
