UPX is a program that allows you to immediately package executable files, after which they will take up a minimum of space on your computer's hard drive, and at startup will be unpacked directly into the computer's memory.

The UPX program supports a large number of file formats, including COM, EXE and SYS.

Great software for saving space on your laptop. My computer is a bit old, and running out of space. After using UPX, my laptop runs a lot faster now. Would recommend this to anyone with slightly older laptops or looking to save space.
UPX is an application that can compress executable files by up to 70%. The executables can then be decompressed with no change to their usability and stability. UPX supports multiple types of executables and scripts. UPX is good to use to more easily store a large number of files. UPX is considered generally stable and safe to use. Another great feature is that the application is open source.
