What do you use to minimize and compress JavaScript libraries?

Sometimes you'll see two different files like "jquery.1.3.2.js" and "jquery.1.3.2-min.js". The "min" version has all the whitespace and comments removed.

Is there a tool that will do that for me or do I have to do it manually?

Answer 1

Yes. The term you're looking for is "minify" your javascript.

Jsmin, Packer, and ShrinkSafe are all good tools. But the leader is YUI Compressor.
