title: Can a PNG be optimized in a browser via JavaScript?
body: <p>I have been using tools like <a href="http://optipng.sourceforge.net/" rel="nofollow">OptiPng</a> for a long time and am wondering if there is any equivalent, that runs in JavaScript only inside the browser.</p>
  
  <p>Just curious if a framework/plugin exists to optimize images in JavaScript?</p>
