CSS Compressor

This tool written in javascript so it's all client side (no transmitting your CSS to someone elses' server), and it has a few more capabilities, plus configurable options. It basically takes out comments and whitespace from a CSS file, which can save more space than you might imagine.

Options (NoteThis strips /* */ style comments. This is the only valid type of CSS comment. This could screw with browser hacks, you might prefer 'strip long comments'.)
(NoteSimilar to above, but will only strip comments with the number of characters you specify inside them. Will match less browser hacks.)
(NoteWhen unchecked, all newlines will be removed. Checking this box will place a newline between each separate rule.)
