This plugin will optimize your images exactly like Google Pagespeed Insights
This plugin is for all those people who are struggling with Google saying their images can be optimized better.
We make use of the Google PageSpeed API. Therefor it has the exact same compression as Google PageSpeed. It just works out of the box (if API key is set).
The best of it, we do NOT make the image a lower quality one! 
The plugin will NOT resize images! If your theme serves image too big and resizes them by simply scaling it with CSS than there is a change it will not optimize as you might think!
If you want a demonstration for a specific image, just ask me and I will upload it in my site and show you the results.
For the premium version check <a href="https://codecanyon.net/item/wp-google-pagespeed-insights-image-optimizer/20596917" rel="nofollow ugc">WP Google PageSpeed Insights Image Optimizer Pro</a>
Here you get:
<ul>
<li>Bulk optimize</li>
<li>Backup your originals</li>
<li>Restore originals</li>
<li>Optimize theme images</li>
<li>Before / after slider (see the comparison)</li>

WP Google PageSpeed Image Optimizer Lite

This is the best plugin by far. Google Pagespeed will nog bother you anymore with images that are not compressed enough.

Previous plugins did optimize, bug Google Pagespeed always said it could improve more.
With this plugin this is gone.

Best image compression plugin by far!

Best plugin for Google Pagespeed

I’m looking for an optimization plugin that can bring image sizes down to Google PageSpeed suggested size. I don't know what the deal is, but even with this plugin using the official API my image is still 30% larger than PageSpeed wants.

Testing with a 193kb jpg (700×467):

Smush Image Compression and Optimization: 145kb (24.8%)
Imagify: 145kb (24.8%)
Compress JPEG & PNG images (by TinyPNG): 145kb (24.8%)
EWWW Image Optimizer: 101kb (47.6%)
WP Pagespeed by R3dRidl3: 99kb (48.7%)
Google PageSpeed: 69kb (64.2%)

Still searching for a better solution…

Good, but still not as good as pagespeed
