DPI Metadata vs Actual Pixels: What Really Happens?
On Digital Screens (Phones / Laptops)
Screens only care about pixels. An image that is 600 × 800 pixels will look identical on your screen whether its DPI metadata is set to 72, 200, or 300 DPI.
On Physical Paper (Printers & ID Cards)
Printers use DPI to calculate physical size: 600 pixels printed at 300 DPI produces exactly 2 inches (5.08 cm) of crisp physical paper print.

Image DPI – Frequently Asked Questions
No. DPI (Dots Per Inch) is simply metadata in the file header that tells printers how densely to lay ink dots. It does not alter your picture pixel dimensions on computer screens.
