About formats

JBG is a file extension for images compressed using the JBIG (Joint Bi-level Image experts Group) standard, formally ITU-T Recommendation T.82, completed in 1993 as a successor to the Group 3 and Group 4 fax compression standards. JBIG compression is designed for bi-level (black and white) images but can also handle grayscale and limited-color images by encoding each bit plane separately. The algorithm uses a form of arithmetic coding guided by an adaptive context model: for each pixel, the encoder examines a template of surrounding already-coded pixels to build a probability estimate, then feeds this estimate to a QM-coder (a variant of the Q-coder arithmetic coder) that produces a highly efficient binary output. JBIG achieves 20-40% better compression than Group 4 on typical document images, with the improvement being even larger on halftoned photographs and images with gradual density transitions where Group 4's simple run-length approach is less effective. The standard supports progressive encoding, where a low-resolution version of the image is transmitted first and progressively refined — useful for fax-like applications where the receiver can begin displaying the image before the full-resolution data arrives. One advantage is superior compression of documents containing halftone images: newspapers, magazines, and marketing materials that mix text with photographic halftones compress dramatically better with JBIG than with Group 3/4. The standard's ITU-T backing ensures it is implemented in document imaging hardware and software worldwide. JBG files are supported by ImageMagick and various document imaging tools.

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.
