How to Check the DPI of an Image
Upload or drop the image into the checker below. It reads the file’s embedded resolution metadata locally and shows the X/Y value, format, and pixel dimensions. If the file has no usable resolution field, the result is Not specified. That is different from having no pixels or having a low-quality image.

Print reality check
Will it work at your print size?
Pixel dimensions—not a metadata label—determine usable print detail.
Choose an image, then check a print size.
DPI and PPI are related, but not identical
DPI describes dots produced by a printer. PPI describes pixels per inch in an image or layout. Image files commonly store a PPI-style resolution value, even when people casually call it DPI. The checker reports the metadata value without pretending it measures printer output.
What the result tells you
The result combines the embedded resolution with width and height in pixels. A file can report 300 DPI and still be too small for a large print. Another file can have no resolution metadata while containing enough pixels for your intended size. For print planning, divide pixel width and height by the target DPI to estimate the available physical size.
When metadata is not specified
“Not specified” means the file did not provide a reliable resolution source the tool could read. It is not a quality score. Ask the printer, designer, or publishing system what target DPI it expects, then compare that target with the image’s pixel dimensions.
