What is a EPUB file?
EPUB (Electronic Publication) is a widely adopted open eBook format maintained by the W3C. It uses HTML and XML to structure content, making it highly adaptable to different screen sizes and devices.
EPUB files support rich formatting, images, and embedded fonts, and are compatible with most eBook readers, including Apple Books, Kobo, and many Android apps. It is often preferred for its flexibility and non-proprietary nature.
How to open EPUB files
EPUB files can be opened using Apple Books, Google Play Books, Kobo, and many eReader apps on Android and iOS. Desktop users can use Calibre, Adobe Digital Editions, or browser plugins like EPUBReader.
AnyConv allows you to convert EPUB files to PDF, MOBI, or AZW for compatibility with Kindle or other platforms.
