PECompact is an advanced Windows executable compressor for use by software developers and vendors. Executable packers compress executable modules (EXE, DLL, etc..) so that their physical size is considerably smaller. At runtime, compressed modules are rapidly decompressed and reconstructed in memory. Used on Google Desktop, DivX Player 6.0, and hundreds of other popular software products, PECompact has real-world exposure and testing beyond competing products. With PECompact, you can rest assured your compressed software will be trouble free.

PECompact performs better than other industry competitors in both compression ratio and decompression speed, but most importantly it is commercial ready software that is constantly updated and maintained. The decompression algorithms used by PECompact are optimized for maximum decompression speed. This results in the load time of compressed modules often being improved since fewer bytes must be read from the storage medium. Additionally, the compression ratio of PECompact is better than any general purpose compression software like ZIP, RAR, or 7-ZIP. This is because PECompact is optimized for a specific type of file format: executables. The compression ratio typically ranges from 70% to 80%, but varies depending on the specific module.
