About formats

HTML (HyperText Markup Language) is the standard markup language for creating web pages, originally conceived by Tim Berners-Lee at CERN in 1991 and later standardized by the W3C and WHATWG. HTML structures content using a system of nested tags that define headings, paragraphs, lists, links, images, tables, forms, and multimedia elements, with CSS handling visual presentation and JavaScript adding interactivity. The language has evolved through major versions — HTML 2.0 (1995), HTML 4.01 (1999), XHTML 1.0 (2000), and the current HTML Living Standard (evolved from HTML5, published 2014) — each expanding semantic vocabulary and capabilities. HTML documents are plain text files interpretable by any web browser, and the language's role extends beyond websites: email formatting, ebook content (EPUB), application interfaces (Electron, Cordova), and document export all rely on HTML. One advantage is universal rendering — every computing device with a browser displays HTML content, making it the most widely supported document format in existence. The semantic markup model provides another strength: elements like <article>, <nav>, <aside>, and <figure> carry meaning that benefits accessibility tools, search engine indexing, and content reuse. The open, W3C/WHATWG-governed specification ensures vendor independence, and HTML's text-based nature means documents are trivially created, inspected, and processed with any programming language.

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.
