LZO 2.08

Free and open source data compression library
LZO is a data compression library which is suitable for data de-/compression in real-time. This means it favours speed over compression ratio.

Both the source code and the compressed data format are developed in ANSI C to be portable across platforms.

LZO is also reported to work under Mac Classic, Mac OS X, AIX, AmigaOS, ConvexOS, CrayOS, Dreamcast, FreeBSD, IRIX, MiNT, NetBSD, Nintendo64, OpenBSD, OS/400, PalmOS (Pilot), PlayStation, QNX, Solaris, SunOS, TOS, WinCE, VMS, VxWorks, Wii and Xbox.

Main features:

  • Decompression is simple and *very* fast.
  • Requires no memory for decompression.
  • Compression is pretty fast.
  • Requires 64 kB of memory for compression.
  • Allows you to dial up extra compression at a speed cost in the compressor. The speed of the decompressor is not reduced.
  • Includes compression levels for generating pre-compressed data which achieve a quite competitive compression ratio.
  • There is also a compression level which needs only 8 kB for compression.
  • Algorithm is thread safe.
  • Algorithm is lossless.
