Great plugin, easy to use, helped boost Google Page Speed score.

I have been using this plugin on all of my websites for about a month and have not had any negative effects. There’s not a lot to it, you just install the plugin, activate it, and Smush (compress) your images. It helps with Google Page Speed and GTMetrix scores. It will also automatically Smush newly uploaded images. I am going to end up purchasing the pro version very soon.
