JB2 to JPEG Conversion: FAQ

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.

What are JPEG files?

JPG or JPEG is a commonly used method of lossy compression. JPEG compression is used in a number of image file formats. JPEG/Exif is the most common image format used by digital cameras and other photographic image capture devices; it is the most common format for storing and transmitting photographic images on the internet.
