I fully agree with j3rkules about any plugins not updated from 3 years.
I've tried
https://wordpress.org/plugins/imagem...esized-images/
Plug-in says ImageMagick is installed as on this screenshot
https://ps.w.org/imagemagick-sharpen...ng?rev=1738783
but it doesn't sharpen my Wordpress thumbnails as many TGPs software were able to do it.
