What Does DPI Mean in Images?
DPI stands for Dots Per Inch. It is a measurement that printers use to determine how tightly ink dots are packed on paper. The difference between 300 DPI and 72 DPI is crucial: 300 DPI is required for sharp, professional printing, while 72 DPI is the standard for web displays. Our tool simply adjusts the DPI metadata inside your file, meaning you change image DPI without resizing pixels or losing visual quality. If you also need to adjust the pixel dimensions of your image, you can use our Resize Image tool.
