The higher the DPI, the better the image quality

DPI stands for Dots Per Inch. DPI is not really a part of the image itself, and doesn’t change anything within the image. It’s a number that’s stuck onto the side that tells a printer how big it should print out the image. If the image is 72 DPI, the printer will print out 72 dots in every linear inch. At 300DPI, the printer will print 300 dots in every linear inch. Not all the graphic formats support the DPI setting, but with those that do ImageConverter Plus allows changing image DPI in batch mode when you resize your images. Simply insert the desired DPI parameter and get the result within seconds.
