FAQ
JB2 to QOI Conversion
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 QOI files?
QOIQOI (Quite OK Image) is a fast, lossless image format designed as a simpler alternative to PNG. It offers similar compression quality but with much faster encoding/decoding speeds, making it ideal for applications where performance matters.
