EPUB (Electronic Publication) is an open ebook standard developed by the International Digital Publishing Forum (IDPF), now part of the W3C. First released in 2007 as a successor to Open eBook, EPUB has become the most widely supported ebook format. EPUB files are ZIP archives containing HTML/XHTML content, CSS styling, images, and metadata organized according to the EPUB specification.

EPUB's key feature is reflowable content—text automatically adapts to different screen sizes, making it ideal for e-readers, tablets, and phones. The format supports embedded fonts, multimedia (in EPUB 3), and accessibility features. Most e-readers except Amazon Kindle natively support EPUB.
DOCX is Microsoft's modern Word document format based on Office Open XML (OOXML), standardized as ISO/IEC 29500. Introduced in Office 2007, DOCX stores content as compressed XML files inside a ZIP container, supporting rich text formatting, embedded media, styles, templates, and change tracking. Unlike the legacy binary DOC format, DOCX is more compact, less prone to corruption, and easier for third-party applications to parse.

DOCX is the standard for collaborative document editing and remains fully compatible with Microsoft Word, Google Docs, LibreOffice, and most document processors. For final distribution or archival, consider converting to PDF.
