What is ePub ebook format?


EPUB is an e-book file format with the extension .epub that can be downloaded and read on devices like smartphones, tablets, computers, or e-readers. It is a technical standard published by the International Digital Publishing Forum (IDPF). The term is short for electronic publication and is sometimes styled ePub. EPUB is the most widely supported vendor-independent XML-based (as opposed to PDF) e-book format; that is, it is supported by the largest number of hardware readers. ePub is based on xHTML, XML and CSS.



The format and many readers support the following:

• Reflowable document: optimize text for a particular display
  
• Fixed-layout content: pre-paginated content can be useful for certain kinds of highly designed content, such as illustrated books intended only for larger screens, such as tablets.
  
• Like an HTML web site, the format supports inline raster and vector images, metadata, and CSS styling.
  
• Page bookmarking
  
• Passage highlighting and notes
  
• A library that stores books and can be searched
  
• Re-sizable fonts, and changeable text and background colors
  
• Support for a subset of MathML
  
• Digital rights management—can contain digital rights management (DRM) as an optional layer
  

The EPUB specification does not enforce or suggest a particular DRM scheme. This could affect the level of support for various DRM systems on devices and the portability of purchased e-books. Consequently, such DRM incompatibility may segment the EPUB format along the lines of DRM systems, undermining the advantages of a single standard format and confusing the consumer.
