About formats

MOBI is an ebook format originally developed by Mobipocket SA, a French company founded in 2000 that was later acquired by Amazon in 2005. The format builds on the PalmDOC/PDB container structure, adding support for HTML-based content markup, embedded images, a DRM layer, and a JavaScript subset for limited interactivity. MOBI files use a record-based database architecture inherited from Palm OS, with a header structure containing metadata like title, author, publisher, and language followed by compressed HTML content records. The format became the foundation of Amazon's early Kindle ecosystem — the original AZW format used on first-generation Kindles was essentially MOBI with Amazon's own DRM wrapper. MOBI supports reflowable text with basic formatting including bold, italic, headings, lists, and tables, as well as internal hyperlinks and a built-in table of contents. One advantage is broad device compatibility: MOBI files are recognized by Kindle devices and apps spanning over a decade of hardware, as well as numerous third-party readers on desktop and mobile platforms. The format's lightweight structure is another strength — even long novels produce compact files that load quickly on modest hardware. While Amazon has since moved to the more capable AZW3/KF8 format for new publishing, MOBI remains widely circulated in existing ebook libraries and continues to be produced by conversion tools like Calibre for maximum Kindle compatibility.

EPUB (Electronic Publication) is an open ebook standard originally developed by the International Digital Publishing Forum (IDPF) and now maintained by the W3C following the organizations' merger in 2017. The first version carrying the EPUB name was approved in October 2007 as a successor to the Open eBook Publication Structure (OEBPS). An EPUB file is essentially a ZIP archive containing XHTML or HTML5 content documents, CSS stylesheets, images, fonts, and metadata organized according to the Open Packaging Format and Open Container Format specifications. The current major version, EPUB 3, supports reflowable and fixed-layout content, embedded multimedia, JavaScript interactivity, MathML equations, and rich accessibility features including semantic markup and media overlays for synchronized text and audio. A defining advantage is universal device support — unlike proprietary formats, EPUB works natively on virtually every non-Kindle e-reader, tablet, and reading application, from Apple Books and Google Play Books to Kobo and dozens of third-party apps. The reflowable text model is another core strength, automatically adapting pagination, font size, and margins to match any screen dimension and user preference. EPUB's open specification and active W3C stewardship ensure long-term preservation and vendor independence, making it the de facto standard for digital publishing across libraries, academic institutions, and commercial retailers worldwide.
Initial release: October 2007
