A command line archiving program for manipulating zip files. 7-zip features great compression ratios, support for quite a few other archive formats, and is free.
DataCompression.info user Gregg A. had this to say: 7-Zip is a great archiver that works with many of the popular archive formats, as well as a new one of its own. This is my favorite compression tool now because it is so universal and it’s open-source.

w3compiler

This is a compiler for web pages, that uses various techniques to squeeze the fat out of your web pages. This includes things a simple as white-space reduction and as complex as JavaScript compression.

Ron M. had this to say: This is a great program, very highly recommended for Web developers. It lets you write your code full of comments and extra space for readability, and then strips it all out automatically for the live site. My pages have been noticeably faster & very hard to decipher the code on the other end. It’s been reliable and easy to get used to.
