WP-HTML-Compression

Combining HTML «minification» with cache and HTTP compression (WP Super Cache, or similar) will cut down your bandwidth and ensure near-immediate content delivery while increasing your Google rankings.

This plugin will compress your HTML by shortening URLs and removing standard comments and whitespace; including new lines, carriage returns, tabs and excess spaces. Most importantly, by ignoring <pre>, <textarea>, <script> and Explorer® conditional comment tags, presentation will not be affected.
