wadptr - WAD compressor

wadptr is a utility for reducing the size of Doom WAD files. The "compressed" WADs will still work the same as the originals. The program works by exploiting the WAD file format to combine repeated/redundant material.

The source code is portable and will run on most Unix systems as well as Microsoft Windows. The program is Free Software under the GNU GPL v2+.

There is a manual page that describes how to use the program.

For the latest developments, you can follow the project on Github.

Andreas Dehmel's ports of wadptr to RISC OS and Solaris. These are based on a very old version nowadays but may still be useful to someone.
Minimalist IWAD, a tiny Doom IWAD file less than 250KiB in size that makes heavy use of wadptr to achieve its small size.
Squashware Doom is a version of the Doom shareware IWAD file shrunk to under 2MB by making clever use of wadptr's compression techniques.
Doom for the Nintendo Game & Watch, which uses wadptr to cope with the restrictive size requirements.
John Romero used wadptr for SIGIL II!
