I use YUICompressor . It works on both JavaScript and CSS. Once it's installed, it's easy to use:

Unfortunately, you will need to manually run the compressor every time you change the original file, which can get tedious if you're working with lots of files. If you want to automate the process, see this answer . I ended up writing a quick batch script for my project.
