A digital photo is described in pixels, but it might confuse someone who is more experienced with centimeters or inches. It is also important when you need to get a specific image size (e.g. 6×4 inches) with a specific resolution (e.g. 300 DPI). It won’t take much of your effort apart from choosing the desired size and DPI. As soon as you do it, ImageConverter Plus will adjust the required image size automatically.
