gzip is a compressed file format and command line utility used primarily on Unix-style operating systems, but available cross-platform. It uses DEFLATE compression.

Contents

Identification

gzip files begin with two signature bytes: 0x1F 0x8B. The third byte indicates the compression method, and is normally 0x08 (meaning DEFLATE).

gzip 0.5 apparently used Freeze/Melt 1.x format, with signature bytes 0x1F 0x9E.
