This tool I wrote is a Windows application that allows you to interact with the Microsoft Ajax Minifier without using the command line or Visual Studio. With this GUI tool you can do the following:
- browse to the JavaScript file to be minified
- run the minifier in the background
- enable/disable the minifier’s hypercrunch and analysis options
- open the output folder once the minifier finishes
- view the minifier’s output

More information about the Microsoft Ajax Minifier
The Microsoft Ajax Minifier reduces the size of a JavaScript file by removing unnecessary content from the JavaScript file. The tool supports two modes: normal crunching and hypercrunching.
In normal crunching, the tool strips comments, unnecessary whitespace, curly-braces, and semicolons from a JavaScript file. In hypercrunching mode, the the tool shortens the names of local variables (variables in functions but not global variables) and removes unreachable code.
