About formats

KWD is the native document format of KWord, the word processor component of KOffice (later renamed Calligra Suite), developed by the KDE community with its first stable release in KOffice 1.0 in 2000. KWord distinguished itself from other word processors through a frame-based layout model where text, images, and other content existed in independent frames that could be positioned freely on the page, similar to desktop publishing applications — a departure from the linear text-flow approach used by most word processors. KWD files store document content in a compressed XML format that describes the frame hierarchy, text content with formatting markup, paragraph styles, page dimensions, headers, footers, and embedded media. The format uses a ZIP container packaging the XML document alongside any referenced images and resources. One advantage was the flexible frame-based layout — users could position text and image frames independently on the page, enabling newsletter-style layouts and creative document designs without switching to a dedicated DTP application. The open XML structure is another benefit, making KWD files transparent and accessible to automated processing. KWord was included in several Linux distributions as part of the KDE desktop environment during the 2000s. The project was eventually discontinued in favor of Calligra Words, which adopted the ODF standard. KWD files can be opened with legacy KOffice installations or converted through document conversion tools.

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.
