What a great tool

Exactly what I was looking for!

I was being unsatisfied with WordPress native residing of images, because even at 100 compression they look blurry at small sizes. With that plugin resided images look great and also I can set compression what I choose. The default compression in the plugin is set at 62, the default compression in WordPress is 82, but for a photography site, which I am building, I found it is better to set it at 90. And btw the compressed images at 90 are smaller than the ones I compress in Lightroom, and they look the same!

Huge thanks to the developer! Amazing job!
