It is a tool to mutually convert the print size of an image and the number of pixels. It helps to determine whether a date can be used as a publication or commercial print.
When you want to know the number of pixels required for the planed range of the printing, the print size from the number of pixels of an image and the print size from an image size displayed on a screen, this tool will be useful. It can also convert a paper size to the number of pixels.
