Image DPI Checker
Check an image’s pixel dimensions and, when available, embedded DPI or density metadata. Files are read locally in your browser.
Check Image DPI and Resolution
This tool reads pixel dimensions and, when present, embedded density metadata from PNG and JPEG files. It helps distinguish pixel resolution from print-density metadata.
Practical Example
A 3000-pixel-wide image with embedded 300 DPI metadata corresponds to an approximate print width of 10 inches because 3000 ÷ 300 = 10.
Factors That Affect the Result
Many web images contain no embedded DPI value at all. That does not mean they lack resolution—their pixel width and height still determine image detail. Physical print size depends on the target pixels-per-inch used in the print workflow.
Frequently Asked Questions
Does changing DPI create new detail?
No. Metadata alone does not add pixels.
Is 300 DPI always required?
No. The appropriate density depends on print size and viewing distance.
Is the file uploaded?
No. The image is read locally in your browser.

What Image DPI Actually Means
DPI is commonly used to describe print density, while digital images are fundamentally defined by pixel dimensions such as 3000 × 2000 pixels. Image files may also contain resolution metadata that suggests how densely those pixels should be printed. The checker helps inspect this information without changing the image.
DPI, Pixels, and Print Size
A high DPI value does not create extra detail if the file has too few pixels. Print size depends on both pixel dimensions and the intended print density. For example, a 3000-pixel-wide image printed at 300 pixels per inch is about 10 inches wide. The same pixels printed larger produce a lower effective density.
How to Interpret the Result
Use pixel dimensions first when judging digital quality. For print work, compare those dimensions with the required physical size and the printer or publisher's recommended resolution. Some images have no meaningful DPI metadata at all, which does not automatically mean they are low quality. Social media and web displays generally care more about pixel dimensions, compression, file format, and responsive sizing than embedded DPI metadata.
