  1. I don’t understand how these percentages can be meaningful without evaluating the quality of the resulting product. I can reduce images by 20-80% in Photoshop by changing the JPEG quality, but at some point they degrade and below that they look awful. Did you compare the quality of the results, looking for artifacts, color changes, perceived sharpness?
