Free Image DPI Checker & Print Size Calculator

DPI tips
Check DPI instantly
Upload any JPEG or PNG and the tool reads the embedded DPI from the file header. If no DPI is stored, it shows the pixel dimensions so you can decide.
See print sizes
Enter a target DPI and see the exact print dimensions in inches and centimeters. A color-coded badge tells you whether the resolution is enough for sharp prints.
Compare print formats
A quick table shows how your image maps to common print sizes — from wallet to 16 by 20 — with a quality grade for each.
Stays on your device
The DPI is read in your browser. Your photo is never sent to a server and the file header is parsed locally.
