Image DPI Checker: Check the DPI of an Image Online
Upload a JPEG or PNG to see its DPI, pixel size and print size in seconds. Find out if it’s ready for 300 DPI printing. Free, no signup.
Check Image DPI in Seconds
Printers, publishers and print shops ask for 300 DPI files, but most image viewers hide that number. This DPI checker reads the resolution stored in your image and shows it next to the size it will print at.

See Pixel Size and Print Size Together
DPI alone doesn’t tell you how big a photo will print. The tool shows the pixel dimensions and works out the print size in inches and centimetres, so you know exactly what you’re working with.
Know if Your Image Is Print-Ready at 300 DPI
Next to the detected DPI, the checker shows how large the image would print at 300 DPI, the standard for sharp prints. If that size is smaller than you need, find a larger original before you send it to print.
Check Photo DPI Without Photoshop
No editing software needed. Upload a JPEG or PNG up to 5 MB and the photo DPI appears instantly. It works in your browser on Windows, Mac, Android and iPhone.
Export the Results as JSON
Need the numbers in a report or a script? Export the DPI, dimensions and print sizes as JSON, ready to save or share with a designer or developer.
Image DPI, Not Mouse DPI
This tool checks image resolution, the dots per inch used for printing. Mouse DPI measures cursor sensitivity, which is a hardware setting you check in your mouse software instead.
