Electronic Publication (EPUB) is the open standard for e-books and the format used by almost every retailer except Amazon. An EPUB is really a ZIP package of HTML, CSS, images, and fonts, which means the text reflows to fit whatever screen it is read on. Readers can change the font, size, and margins freely, and the same file works on phones, tablets, e-readers, and computers.

 

How to open an EPUB file?

On Apple devices, EPUB opens directly in Apple Books. On Windows and Android, Calibre is the standard choice and doubles as a library manager and converter.

 

Other good readers are Adobe Digital Editions, which handles DRM-protected library loans, plus Thorium Reader, Google Play Books, and Kobo. Amazon Kindle devices now accept EPUB through Send to Kindle, but for older Kindles convert the file first with our EPUB to MOBI tool.
