I find that I can convert color PDF files to color PNG files, IF there is not a scan in the chain of creation. If the color PDF is made from a scan, I cannot seem to get the resultant png file to be small enough (provided the PDF is 300 dpi and 8½ x 11).
Has anyone been able to scan to a color PDF, then save as a color PNG, and have the PNG file 500kb or smaller?
