FUPX (also known as Free UPX) is a free, advanced graphical interface for UPX (the Ultimate Packer for eXecutables) from Pazera Software.
Although there are other executable file compressor alternatives, FUPX will provide you access to all UPX parameters, and you can use the program an EXE file analyzer.
UPX has been a rising star in the world of file compression. Rather than having to deal with the unreliable and lossy nature of .zip files, UPX offered a whole set of new solutions and a wider variety of file types. FUPX adds a significant quality of life improvement for UPX by giving it something that is needed for the longest time: a graphic interface.
FUPX isn’t just a simple GUI for UPX; it also comes with some advanced features that make it well worth an install.
Let’s take a closer look at FUPX and all of its features.
