SEO Image Optimizer Wizard

Absolutely Amazing App - I am working on my site SEO and pulled a Page Insight only to find that the site speed score was slowed down by large png's. I have a lot of product images and to go through all to re. size it would have been a nightmare, luckily I came across this app after other have failed to deliver and in the most absolute honesty it has delivered; it is straight forward to use, humane, free and whoever runs this is an all round amazing human being !!!!!! Thanks
