Combining HTML “minification” with cache and HTTP compression (<a href="https://wordpress.org/extend/plugins/wp-super-cache/" rel="ugc">WP Super Cache</a>, 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 <code><pre></code>, <code><textarea></code>, <code><script></code> and Explorer® <code>conditional comment</code> tags, presentation will not be affected.

WP-HTML-Compression

Reduce file size by shortening URLs and safely removing all standard comments and unnecessary whitespace from an HTML document.
