About the G4 format
G4 — CCITT Group 4 FAX
G4 is the more advanced monochrome fax compression format defined by ITU-T for Group 4 fax machines and TIFF storage. Using Modified Modified READ (MMR) compression, it achieves significantly better compression than G3 and is the standard for TIFF-based document archiving.
Common uses
- High-compression document fax archiving
- TIFF G4 document scanning for records management
- Legal and government document storage
- Converting G4 fax archives to PDF
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
