# IisGzip

IisGzip is a command line wrapper around the [gzip compression library](http://msdn.microsoft.com/en-us/library/dd692872.aspx) used by Microsoft IIS.

If you're looking for a way to let IIS compress content using a different compressor, check out [this other project](https://github.com/mganss/ZopfliDll).

## Usage

```

IisGzip.exe [-0..10] [-dPathToDll] < in.txt > out.txt.gz

```

Default compression level is 10. Make sure you have IIS installed.

## Performance

Here are a few completely unscientific benchmarks:
