UPX EXE Compressor GUI 3.2.2 is a simple PyQt5-based graphical interface for compressing and decompressing Windows executable files with UPX. It is designed for users who want the power of UPX without typing command-line options manually.
The app supports EXE compression, decompression, adjustable compression levels, optional backup creation, overwrite handling, CFG warning checks, multilingual UI, theme selection, recent files, UPX path configuration, and persistent settings saved in the Windows Registry. The latest version also adds UPX auto-detection, LZMA compression, drag-and-drop support, file analysis, output-folder opening, and command copying.
