About formats

AI (Adobe Illustrator Artwork) is the native file format of Adobe Illustrator, the industry-standard vector graphics editor first released in January 1987 for the Apple Macintosh. Early versions of the format were based on the PostScript page description language, with each file being a conforming EPS document that could be placed in other layouts and interpreted by PostScript printers. Starting with Illustrator 9 in 2000, Adobe transitioned the AI format to a PDF-based structure, embedding Illustrator-specific editing data within a valid PDF wrapper — this dual nature means modern AI files can be opened in any PDF viewer for display, while preserving the full editable artwork including layers, artboards, and live effects when reopened in Illustrator. The format supports complex vector constructs like gradient meshes, clipping masks, symbol libraries, transparency blending modes, and multiple artboards within a single document. One significant advantage is lossless scalability — artwork maintains perfect precision at any size, from favicon to billboard, because geometry is defined mathematically rather than as pixels. Deep integration with the Adobe Creative Cloud ecosystem is another strength, enabling seamless round-tripping between Illustrator, Photoshop, InDesign, and After Effects without format conversion. AI remains the de facto standard for professional illustration, logo design, and print production workflows worldwide.

JBIG (Joint Bi-level Image experts Group) is a lossless image compression standard (ITU-T T.82) published in 1993, developed by a committee of experts drawn from the same international standards bodies that created JPEG. While the extension .jbig and .jbg refer to the same underlying compression standard, .jbig is the more explicit form commonly used in software that handles the raw JBIG-compressed datastream. The compression algorithm centers on context-dependent arithmetic coding: before encoding each pixel, the encoder examines a configurable template of 10 to 16 nearby pixels (a mix of neighbors from the current and previous lines) to determine a context — one of thousands of possible local pixel configurations. Each context maintains its own adaptive probability estimate that is continually updated as encoding proceeds, allowing the coder to exploit the statistical patterns unique to each image region. This approach handles text, line art, halftoned photographs, and mixed-content pages with a single algorithm, achieving consistently better compression than the fixed Huffman tables of Group 3 or the simpler prediction model of Group 4. A later revision, JBIG2 (T.88), added pattern matching and lossy modes for even higher compression, but the original JBIG remains widely deployed. One advantage is the algorithm's adaptiveness: unlike Group 3/4 codecs that use fixed statistical models, JBIG continuously learns the characteristics of each specific image as it encodes, providing near-optimal compression across widely varying content types. The standard is embedded in many multifunction printers and document scanners for internal image handling. JBIG files are processable by ImageMagick, jbigkit, and enterprise document imaging systems.
