What is a .EPUB file?
EPUB is the open ebook format used by most readers - a zipped package of HTML and assets. Opened in Apple Books, calibre and most e-readers.
- Did you know
- EPUB was released in 2007 by the International Digital Publishing Forum and is the standard everywhere except Amazon Kindle.
- EPUB grew out of the earlier Open eBook Publication Structure, the standard that the International Digital Publishing Forum first approved at the end of the 1990s.
- Stewardship of the format passed to the World Wide Web Consortium after the IDPF merged into it, and modern EPUB 3 is built from web technologies like XHTML and CSS.
- Under the hood a .EPUB file is really a ZIP archive - rename it to .zip and you can browse the files inside.
- On the web a .EPUB file is served with the MIME type
application/epub+zip.
