UPX 原文簡介:

The program is a free, portable, extendable, high-performance executable packer for several executable formats.

The program strengths in a nutshell:

Secure: as the program is documented Open Source since many years any relevant Security/Antivirus software is able to peek inside UPX compressed apps to verify them.

Excellent compression ratio: typically compresses better than Zip, use UPX to decrease the size of your distribution!

Very fast decompression: more than 500 MB/sec on any reasonably modern machine.

No memory overhead for your compressed executables because of in-place decompression.

Safe: you can list, test and unpack your executables. Also, a checksum of both the compressed and uncompressed file is maintained internally.

universal: the program can pack a number of executable formats, including Windows programs and DLLs, macOS apps and Linux executables.

Portable: the program is written in portable endian-neutral C++.

Extendable: because of the class layout it’s very easy to add new executable formats or new compression algorithms.

Free: the program is distributed with full source code under the terms of the GNU General Public License v2+.
