Best of its kind

I have used the free version for a week and optimized 3 sites. I have images on WC shops and blog pages. Plugin reduced my main site from 3.79GB to 2.09GB, other sites similarly. I used only default settings, didn’t do any customizing. The user interface is clear and intuitive, not crowded. After optimizing images were active in shops and blog and all intact as needed. After optimizing also checked optimized images within my caching plugin (WPFC), all were intact as needed. The only thing I had to repair – the favicon image (what displays logo on browser’s tab) was lost and I had to upload it again. So, excellent job!
