FUPX (formerly Free UPX)

FUPX (formerly Free UPX): A comprehensive GUI for the UPX command line tool

Free UPX is a robust graphical interface for the UPX command line utility, an application designed to pack executable files.

The plain interface lets you load files quickly via drag and drop or through the integrated file browser. For each loaded file you can view its details including name, folder, format, original and packed size, compression ratio, method and packing status among others.

You can choose the output folder to be the one of the original file or use a different location, as well as set the compression type, create backups and force compression. For efficiency, you can simply use one of the predefined profiles.

Free UPX allows you to save BAT files with or without compression and the configurations can be saved as INI files.
