Tools to compress images to pagespeed standard : <p>I've been using Photoshop's "Save for web" option to save images that go on my website.</p>

<p>I keep the quality level at 60 which reduces picture quality slightly. When I increase the level pagespeed tells me that the images can further be compressed without loss.</p>

<p>I've also tried to do the same with Irfan View which has batch resize and compress which is great but results in the same pagespeed warning.</p>

<p>What can I do here? Is there any other tool I can use?</p>
