I have realize that 90%of my images on the site are way to heavy. I got advice from moz either of these two Wp-smush it or Eneable-media-replace , but now I am puzled which to choose, what is better? Will be smush it also able to deal with existing big images without effecting seo.
The smushit is more simpatic for me as they offer also premium support which I would also consider try to help me out with my site.
Thank you very much
