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.

Mobipocket eBook (MOBI) is an e-book format built for handheld devices, storing text as compressed HTML so that it reflows to fit small screens. Amazon bought Mobipocket in 2005 and made MOBI the foundation of the original Kindle format. It supports bookmarks, annotations, and a table of contents, but not the complex layouts or embedded fonts that EPUB allows. Amazon retired MOBI support in 2022.

 

How to open a MOBI file?

Calibre is the most capable option: it reads MOBI, manages your library, and converts between every common e-book format.

 

Older Kindle e-readers and the Kindle desktop app still open MOBI files copied over USB, and mobile apps such as FBReader and Moon+ Reader handle them too. Because Amazon’s Send to Kindle service no longer accepts MOBI, converting your library with our MOBI to EPUB tool is worth doing.
