About formats

WPS is the document format of Microsoft Works, an integrated productivity suite first released in 1987 that bundled a word processor, spreadsheet, and database in a single affordable application. The WPS format stores word processing documents in a compact binary structure that encodes text content, character and paragraph formatting, page layout, headers, footers, and embedded images. Microsoft positioned Works as a consumer-grade alternative to the more expensive and feature-rich Microsoft Office, pre-installing it on millions of OEM personal computers throughout the 1990s and 2000s. This widespread bundling made WPS one of the most commonly encountered document formats in the consumer PC market, even though many users were unaware they were not using "full" Microsoft Word. The format supports basic word processing features including fonts, text alignment, indentation, bulleted and numbered lists, tables, and page formatting, but lacks advanced capabilities like tracked changes, macros, and complex styles found in DOC. One advantage was accessibility — Microsoft Works cost a fraction of Office's price and came free with many PCs, providing capable word processing to millions of home users and students who did not need enterprise features. Microsoft discontinued Works in 2009, recommending migration to Word or the free Office Online tools. WPS files remain present in personal document archives from that era and can be opened by LibreOffice and older versions of Microsoft Office.

G4 is a monochrome image format based on the ITU-T Group 4 facsimile coding standard (Recommendation T.6), ratified by the CCITT in 1984 as an improvement over Group 3 for use on error-free digital networks like ISDN rather than analog telephone lines. G4 files contain 1-bit image data compressed using exclusively two-dimensional Modified Modified READ (MMR) coding, where each scanline is encoded as a set of differences (changing elements) relative to the line above it. By eliminating the one-dimensional coding fallback and the end-of-line synchronization markers required by Group 3, G4 achieves 20-50% better compression ratios on typical document pages while producing a simpler, more regular bitstream. The format is most commonly encountered as a compression method within TIFF files (TIFF compression tag 4), where it became the standard archival format for scanned documents in enterprise document management, government records, and legal imaging systems. G4 compression is specified at 200, 300, or 400 dpi depending on the scanning application, with 300 dpi being the most common for archival-quality document imaging. One advantage is exceptional compression efficiency for document content: G4's two-dimensional prediction exploits the strong vertical correlation in text and line art pages, typically compressing a 300 dpi letter-size page to 30-50 KB — roughly half the size of equivalent Group 3 encoding. The format's entrenchment in document management infrastructure is another strength — G4 TIFF is the mandated format for many government digital records systems, court filing systems, and corporate archives, supported by every enterprise imaging platform.
