Features:
- excellent compression ratio: typically compresses better than WinZip/zip/gzip, use UPX 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: UPX can pack a number of executable formats.
- portable: UPX 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
