About the JBG format
JBG — JBIG Bi-level Image
JBG is an alternate extension for JBIG (Joint Bi-level Image Experts Group) compressed images. JBIG compression is specifically optimized for bi-level (black and white) images and outperforms G3/G4 fax compression, making it useful for fax, document scanning, and monochrome archiving.
Common uses
- High-efficiency fax image compression
- Monochrome document scanning archives
- Converting JBIG compressed fax data
- Black-and-white document storage
About the GZ format
GZ — Gzip Compressed File
GZ is a single-file compression format based on the DEFLATE algorithm, standardized in RFC 1952. Unlike ZIP or TAR, gzip compresses only a single file. It is ubiquitous on UNIX/Linux systems and is used heavily in HTTP content encoding (gzip compression for web pages), log compression, and as the compression layer in TGZ archives.
Common uses
- Compressing individual files on Linux/macOS
- HTTP content encoding for faster web page delivery
- Log file compression on servers
- Single-file distribution with good compression
