About formats

FAX is a generic image file extension associated with facsimile transmission formats standardized by the ITU-T (formerly CCITT), with the underlying Group 3 compression standard ratified in 1980. FAX files typically contain monochrome (1-bit, black and white) image data compressed using the Modified Huffman (MH) encoding defined in ITU-T Recommendation T.4, which assigns variable-length codes to run lengths of consecutive white or black pixels along each scanline. The standard resolution for Group 3 fax is 204x98 dpi (normal mode) or 204x196 dpi (fine mode), reflecting the capabilities of thermal and laser fax machines of the era. FAX files encountered digitally are often raw Group 3 encoded bitstreams or TIFF wrappers with CCITT Group 3 compression (TIFF compression tag 3). The Group 3 encoding scheme is highly efficient for typical business documents — pages with mostly white space and black text — achieving compression ratios of 10:1 to 20:1 compared to uncompressed bitmaps. One advantage is universal fax system compatibility: Group 3 encoding is the mandatory baseline for all fax machines worldwide, meaning FAX files contain data in exactly the format transmitted over telephone lines, preserving the original fax data without transcoding losses. The format's role in business communications history provides another dimension — billions of fax transmissions using this encoding moved legal documents, medical records, and business correspondence for decades, and archived FAX files represent an important documentary record. FAX images can be viewed and converted using LibreOffice, ImageMagick, GIMP, and standard document management systems.

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.
