What is EPUB?
EPUB is the open standard for e-books. An EPUB file is a ZIP package of XHTML chapters, images and a table of contents that reflows to fit any screen, which makes it the default format of Apple Books, Kobo and most e-readers.
Common uses for EPUB
- Reading an e-book as a PDF on a device without an e-reader app
- Extracting the text of a book for notes or search
- Turning an e-book into HTML or Markdown for publishing
Note: DRM-protected EPUB files cannot be converted. Fixed-layout and heavily styled books lose their layout when converted to plain formats.
Compatibility: Apple Books, Kobo, Google Play Books, Calibre and most e-readers. Amazon Kindle needs a conversion first.
