As to your other statement: suggested converting from a losless (PNG) into a lossy (JPG) format as an optimisation (sic!) step is  :facepalm:.

A lot of PNG is not needed to be PNG. I see covers in PNG that are a lot larger then they need to be and saving in JPG cuts the size. I do compare the two images to see if there is a difference and usually not anything noticeable.
