JB2 to DCX 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 DCX files?

DCX files are multi-page images consisting of raster graphics, usually used to create fax files and functioning as a header that introduces a series of ensuing PCX files. DCX is a bitmap format and was initially developed together with the PCX format by Zsoft Corp. and was associated with PC Paintbrush. This graphics editing software was popular in the late 1980s on computers using the MS-DOS operating system, and later on it was adapted for Windows too.
