Image Cleanup

Hi I have Divi and wish to delete all images in the library that are not used in any post or page on my website AND want to delete all files that are size based and also not used. ie

If Upload contains Fish.jpg and Fish_150x150.jpg and Fish_15x15.jpg exist
but only Fish_150x150 is used in website,
Should be able to delete all but that size of Fish

Does the wp-optimize do that? Free version?

Thanks
