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.

RTF (Rich Text Format) is a document interchange format developed by Microsoft and first published in 1987 with Word 3.0. The format encodes document content and formatting as plain ASCII text using control words (backslash-prefixed commands) and groups (curly-brace-delimited sections) that describe fonts, character formatting, paragraph layout, tables, images, and page setup. Because RTF is fundamentally a text format with no binary components, documents pass cleanly through any text channel — email systems, clipboard operations, and cross-platform transfers — without corruption. Microsoft designed RTF explicitly as a cross-application and cross-platform exchange format, and it achieved broad adoption: virtually every word processor, text editor, and document tool on every operating system has supported RTF reading and writing for decades. One advantage is exceptional cross-platform compatibility — an RTF document created on any application renders with consistent formatting on any other, making it the most reliable format for text exchange between incompatible systems. The text-based structure provides another benefit: RTF files resist corruption, are trivially generated by programs (requiring only string concatenation), and can be debugged by reading the raw markup in a text editor. While RTF lacks modern features like tracked changes and advanced layout controls, and Microsoft declared the specification frozen at version 1.9.1 in 2008, the format persists as a dependable interchange option where DOCX compatibility cannot be assumed.
