DotNetGZip™ provides implementations of the GZIP and DEFLATE Internet Standards that offer
higher compression ratios
and more features than the corresponding System.IO.Compression classes of .NET.
It enables you to specify the compression level so that you can balance between performance and compactness,
lets you add a
filename so that the original filename can be restored during decompression and also lets you access other metadata in
the header.
DotNetGZip runs on
both .NET and .NET CF, is written in
100% managed C# code, its assemblies can be distributed
royalty-free, its
full source code is available, and you get a free subscription with every purchase.

Higher compression ratios
We compressed 392 documents using the GZipStream class of DotNetGZip and the GZipStream class of .NET.
The results demonstrated that DotNetGZip can deliver consistently and significantly better compression.
You can read the full details of the size comparisons here. Although these
comparisons examine only XML documents, DotNetGZip offers similar benefits to almost any other type of file.
Selectable compression level
DotNetGZip enables you to select between nine levels of compression, where level 9 provides the best
compression while level 1 consumes the least processing resources. There is also level 0 which uses the GZIP format
but does not compress the stream.
Original filename and other header metadata
Adding a filename to the header metadata enables you to restore the original filename when decompressing.
Other metadata can also be written to or read from the GZIP header.
GZIP and DEFLATE Internet Standards
DotNetGZip implements two Internet Standards, the
DEFLATE Compressed Data Format Specification (RFC 1951) and the
GZIP File Format Specification (RFC 1952),
providing interoperability with implementations on other platforms that are compliant to these standards.
Runs on both .NET and .NET CF
The higher compression ratio offered by DotNetGZip is particularly important for .NET Compact Framework
applications running in low bandwidth environments as every additional reduction in size is significant in improving
communication speed and reducing storage requirements.
Easy to switch
Switching to DotNetGZip brings immediate benefits with minimum effort.
Your existing code can be easily converted to use the classes of DotNetGZip instead of the
System.IO.Compression classes of .NET as the names of the classes are the same and they share the similar interfaces.
DotNetGZip includes an MSDN-style class reference that integrates into the Visual Studio Combined
Help Collection and offers IntelliSense context sensitive help within your project.
You can view the class reference online or download it as a single file from
here. Tutorials are available in the
forums.
