JBIG2 files: Frequently Asked Questions

What are JBIG2 files?

JBIG2 (.jbig2) is a highly efficient bi-level image compression standard aimed at scanned text and document images. Instead of compressing each pixel linearly, JBIG2 analyzes page content to identify and group identical shapes such as letters, numbers, or recurring symbols into a shared symbol dictionary. Each instance is then referenced, dramatically reducing redundancy and achieving compression ratios far beyond traditional CCITT Group 4 or TIFF G4 methods. It can operate in both lossless and lossy modes; the latter achieves extreme compactness at the risk of occasional character confusion. JBIG2 streams are often embedded within PDF or DjVu files and supported by many document imaging systems and multifunction scanners for efficient archival and transmission of monochrome pages.
