JB2 to GBR 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 GBR files?

GBR is part of the Gerber group of formats — a set of standardized extensions used in the printed circuit board (PCB) industry. Gerber files include 2-D representations of various PCB images, such as copper layers, solder mask etc. They can also describe the electrical connections on such boards, or drilling and milling info associated with them. Similar formats include GBS, CMP and SOL.
