Somes tools around zLib built by Gilles Vollant, maker of WinImage and Smartversion.


ZLIB is a compression library compatible with the gzip format. It has been written by Jean-Loup Gailly and Mark Adler. It is free software.
The official page is there, but if you are interested only in Windows 95/98/NT/2000/XP/2003 support, you have found the right place.
There is also a page with a discussion list, Zlib-devel -- zlib compression library development discussions.

This page contains stuff built around zLib by Gilles Vollant, maker of WinImage and Smartversion.
It provides a DLL version of the library and pointers to other projects like MiniZip. It also intends to offer support for the DLL version and for assembly code optimisation.

NEW: the source distribution of the zlib DLL is now merged with the standard zlib.


Current version (1.2.3):

zlib123.zip - zlib-1.2.3.tar.gz - sources of zlib

zlib123dll.zip - pre-built zlib DLL, compiled with the Microsoft Visual studio 2003 compiler (the compiler is available as free download)

zlib122asm_v1a.zip - Latest assembly code for zLib 1.22, both 32 bits (x86) and 64 bits (x86-64 for AMD64/Intel EM64T).

Previous version (1.1.4):

zlib114.zip [146K] (or through FTP) - sources of zlib

zlib114dll.zip [94K] - pre-built zlib DLL

If you want the complete version history for zLib (from 0.95 to 1.1.4), get the multiversion archive zlib.svf, or, from 0.95 to 1.23, zlibnew.svf, and open it with SmartVersion.

Other projects:

Minizip package - Source code that enables to unzip files from a .ZIP file.

sfondo.zip [34K] - full source & exe of an MFC app that uses ZLIB.DLL

gzip124xN.zip [32K] - NT version 1.24 of GNU gzip
