Software developers and engineers who need to reduce executable file sizes for faster distribution and efficient storage without affecting performance
About UPX
UPX (Ultimate Packer for eXecutables) is a high-performance executable compression tool designed to reduce the size of programs and libraries without affecting their functionality or performance. It works by compressing executable files such as EXE, DLL, and other formats across multiple operating systems, including Windows, Linux, and macOS, typically reducing file sizes by 50% to 70%, which helps decrease disk usage, download times, and network load. The compressed executables remain fully self-contained and run exactly as before, as it automatically decompress at runtime without requiring additional dependencies or noticeable memory overhead. UPX uses efficient lossless compression algorithms and supports in-place decompression, allowing programs to execute directly from memory while preserving speed and behavior. It is designed to be secure and transparent, as its open-source nature allows antivirus and security tools to inspect compressed files without obstruction.

Gzip
GNU Gzip is a popular data compression program originally written by Jean-loup Gailly for the GNU project. Mark Adler wrote the decompression part. We developed this program as a replacement for compress because of the Unisys and IBM patents covering the LZW algorithm used by compress. These patents made it impossible for us to use compress, and we needed a replacement. The superior compression ratio of gzip is just a bonus. Stable source releases are available on the main GNU download server (HTTPS, HTTP, FTP) and its mirrors; please use a mirror if possible. gzip reduces the size of the named files using Lempel-Ziv coding (LZ77). Whenever possible, each file is replaced by one with the extension ‘.gz’, while keeping the same ownership modes, access, and modification times. (The default extension is ‘z’ for MSDOS, OS/2 FAT, and Atari.) If no files are specified, the standard input is compressed to the standard output.
