How to Compress JavaScript (JS)

Free Javascript Compressor and Free Obfuscation Tool

Simple - to compress the code so it loads faster

Minification is the practice of removing unnecessary characters from code to reduce its size, thus improving load times. When JS/CSS code is minified all comments are usually removed, as well as unneeded "white space" characters like space, new line, and tab.

With respect to JavaScript, this improves load time performance because the size of the file downloaded is often significantly reduced. Two popular tools for minifying JavaScript code are JSMin and YUI Compressor. Many tools also minify CSS, learn more at MinifyCSS.com.
