What does DPI change?
DPI (dots per inch) is a label in the file that tells printers how large to print it. Changing only the DPI keeps every pixel, so the quality and look stay the same. A 1200×1800 px photo at 300 DPI prints at 10.16 × 15.24 cm.
How do I make a photo 300 DPI at 3.5 × 4.5 cm?
Choose “Resize to an exact print size”, type 3.5 and 4.5 and keep 300 DPI. You get a 413 × 531 px JPG tagged 300 DPI.
