About EPUB
EPUB is the open ebook standard, now maintained by the W3C. An EPUB is a ZIP of XHTML pages, CSS and images, so the text reflows to fit any screen.
Ebooks from most stores and libraries, read in Apple Books, Kobo and Google Play Books, and on Kindle through Send to Kindle since 2022.
Store-bought EPUBs are often DRM-protected, and protected files cannot be converted.

What changes when you convert EPUB to MOBI
- Ebook conversion is best-effort: the text, images and table of contents of the EPUB carry over to MOBI, but layout and styling can change.
- Fixed layouts, embedded fonts and complex styling in the EPUB may not survive the move to MOBI.
- EPUB files can carry DRM copy protection; protected files are detected and refused, because copy protection is never removed.
