JB2 files: Frequently Asked Questions

What are JB2 files?

JBIG2 (.jb2) is a compression format designed specifically for black-and-white, scanned pages. It builds a dictionary of repeated glyphs—letters, digits, logos—so each unique symbol is stored once and merely referenced thereafter, yielding files 5–20 × smaller than fax-style TIFF G4. The format supports both lossless and lossy modes; the latter can introduce character-substitution errors if tuned too aggressively. Widely used inside PDFs and office scanners, JBIG2 offers unmatched compactness for text documents but demands careful settings and secure decoders.
