About

This tool uses the following libraries:

JSMin - Douglas Crockford (Python port by Baruch Even)
Packer - Dean Edwards (PHP port by Nicolas Martin)
YUI Compressor - Yahoo! (written by Julien Lecomte)
Closure Compiler - Google

JSMin is a filter that removes comments and unnecessary whitespace. Packer is a dictionary-based compressor and so the overhead of unpacking the script on the client side may eventually outweight the file size benefits. The YUI Compressor and the Closure Compiler not only reduce the size of your JavaScript code, they also [try to] make it more efficient.
