About EPUB
EPUB (Electronic Publication) is an open ebook standard developed by the International Digital Publishing Forum (IDPF), now part of the W3C. First released in 2007 as a successor to Open eBook, EPUB has become the most widely supported ebook format. EPUB files are ZIP archives containing HTML/XHTML content, CSS styling, images, and metadata organized according to the EPUB specification.

EPUB's key feature is reflowable content—text automatically adapts to different screen sizes, making it ideal for e-readers, tablets, and phones. The format supports embedded fonts, multimedia (in EPUB 3), and accessibility features. Most e-readers except Amazon Kindle natively support EPUB.
