About formats

DOCX is the default document format for Microsoft Word since Office 2007, based on the Office Open XML (OOXML) standard published as ECMA-376 and adopted as ISO/IEC 29500. A DOCX file is a ZIP archive containing XML documents that describe the document body (document.xml), styles, themes, headers, footers, footnotes, comments, numbering definitions, and relationships between parts. Media assets like images and embedded objects reside in dedicated directories within the package. The XML structure means document content is human-inspectable and programmable — developers can create, modify, and extract content from DOCX files using standard XML libraries in any programming language without requiring Word. One significant advantage is openness and interoperability: the published specification enables any software to implement DOCX support, and the format is read and written by LibreOffice, Google Docs, Apple Pages, and dozens of other tools across all platforms. Built-in ZIP compression is another practical strength — DOCX files are substantially smaller than equivalent DOC files, and the modular XML structure improves crash recovery since corruption in one part does not necessarily destroy the entire document. The format supports all modern Word capabilities including SmartArt, content controls, bibliography management, accessibility metadata, and real-time co-authoring. DOCX has become the universal standard for document interchange in business, education, and government.

Initial release: January 30, 2007
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.
