Offzip is designed to scan a file for raw zlib signatures and extract the compressed data. Unlike standard decompression tools (like unzip) that rely on file headers, Offzip blindly scans the file hex data looking for the magic numbers that indicate a zlib stream (usually starting with 78). | Feature | Offzip/Packzip | 7-Zip / WinRAR

Offzip and Packzip are companion command-line utilities developed by Luigi Auriemma, a well-known security researcher and reverse engineer. Unlike standard archivers (WinZip, 7-Zip) that operate on complete file structures (headers, footers, CRC checks), Offzip and Packzip operate on the raw deflate stream level. Offzip is designed to scan a file for

These tools are indispensable for modifying games, firmware, or embedded systems where data is compressed but not stored in standard ZIP/GZIP containers.

To scan data.pak and extract all zlib streams to a folder named output:

offzip data.pak output 0

Note: It typically outputs files named based on their offset in the original file (e.g., 00000001.dat).
