PECompact is an advanced Windows executable compressor. 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.

Executable compressors work by compressing selected portions of executables. At runtime, compressed executables are decompressed and reconstructed directly into their virtual image (memory) so that no data is ever written to the disk. The executable can therefore be run exactly as it was before without the user even knowing it was compressed.
PECompact2 is a next generation win32 executable/module compressor. Commonly termed an 'executable packer', such utilities compress executables and modules (i.e. *.EXE, *.DLL, *.OCX, *.SCR). At runtime the compressed modules are rapidly decompressed in memory.
Why would one want to compress an executable/module?
There are many reasons. One of the most common is that compression offers an inherent degree of tamper resistance and obfuscation. Another is that since the usual compression ratio is greater than 70% (that is, the compressed file is 30% of the original), larger executables and modules may load much quicker from the network or disk hosting them. Since storage medium is often the largest bottleneck in overall system performance, the time spent decompressing can be much less than the time saved by not having to load as much data from the storage medium.
Add tamper resistance.
Obfuscate and help deter reverse engineering.
Compression is typically 70% or greater on large files, far better than popular file compression software. This is because compression is targeted to a specific file/data format.
Load time can be improved by having a smaller image to load from the storage medium (disk, network, etc..).
