EPUB Vs Mobi: What Is The Difference?

As the popularity of eBooks has grown, different eBook formats have emerged including EPUB, MOBI, AZW and PDF eBooks. Confusing? It can certainly be difficult to understand the differences and to identify which format will be most appropriate for your publication.

Hopefully, this blog which compares the difference between two of the most common eBook formats – .epub and .mobi – will help.

GuidingTech.com provides some useful information on EPUB and MOBI, too, available in full at this link.

What Is The Difference Between EPUB VS Mobi?

The main difference between EPUB and MOBI is that EPUB is widely supported across all platforms whilst MOBI is predominantly a Kindle format. The EPUB standard is maintained by the International Digital Publishing Forum (IDPF), a global trade and standards organization. MOBI – which is short for the Mobipocket eBook format – was bought and is managed by Amazon.

EPUB

Considered by many experts as the most common of all the formats, .epub is widely supported across all platforms. Thus, most eReader devices and apps like Apple’s iBooks, Barnes & Noble’s Nook, Adobe Digital Editions, Aldiko on Android among others (in total there are nearly 300) support .epub files. Amazon Kindle is an exception as it does not yet support .epub files.

EPUB format is an open standard. That means it is free and publicly available though there are specific rules for its usage. EPUB can display “reflowable” content – that can adjust its presentation to the output device – and also fixed width layout. It is very similar in appearance to HTML- rendered pages with images.

MOBI

MOBI is also cross-platform and eBooks in this format can have the .prc or .mobi extension. MOBI formats can handle complex content, include advanced navigation controls, support indexing and deal with a high degree of compression. For instance, readers can add their own pages, freehand drawings, annotations, highlights, bookmarks, corrections and notes if their devices support it. MOBI can also include a dictionary.

Because of the 64k image size limitation – at odds with larger display devices like tablets – MOBI format is best suited to smaller screens. Like EPUB, MOBI can display both reflowable content and fixed width layout.
