Großartiges Plugin um Bilder zu optimieren.
Good plugin for compressing images in WordPress. Setup took just a minute, and it started optimizing right away. Site speed improved a bit, too. tnx devs for this.
I needed a lot of images optimised and Smush did the job. Will probably go to Pro level to get some of the additional features.
