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:

excellent compression ratio: typically compresses better than WinZip/zip/gzip, use it to decrease the size of your distribution!
very fast decompression: ~10 MB/sec on an ancient Pentium 133, ~200 MB/sec on an Athlon XP 2000+.
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.
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.
