Image DPI Checker & Changer
Inspect photo Dots Per Inch (DPI/PPI) resolution, calculate physical print dimensions in inches and centimeters, and set target DPI values.
Choose image to inspect DPI and print sizing
Calculate physical print output dimensions at 72, 150, 300, and 600 DPI
Pixel Resolution
0 × 0 Px
Standard Web (72 DPI)
0" × 0"
Medium Print (150 DPI)
0" × 0"
Pro Print Quality (300 DPI)
0" × 0"
Educational Note: Changing an image's DPI metadata tag instructs printers how many dots to render per physical inch on paper. It adjusts the calculated print size but does not magically invent new pixels if the underlying source image has low pixel dimensions.
