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.

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.

Frequently Asked Questions

Why convert AI to JBG?

JBG (JBIG) uses advanced bi-level compression for extremely small files. Converting AI to JBG is ideal for fax, archival, and document imaging workflows.

What opens JBG files?

JBG files open in IrfanView, XnView, ImageMagick, and document imaging software that supports JBIG compression.

Is JBG a monochrome format?

JBIG is primarily designed for bi-level (black and white) images, making it exceptionally efficient for document and text content.

Is AI to JBG conversion free?

Yes — Convertio offers free AI to JBG conversion. Premium plans provide expanded limits for professional needs.

How much does JBG compress images?

JBIG achieves very high compression ratios on bi-level content — typically much better than standard fax compression.
