Free image DPI checker

Check image DPI, pixel size, format, and print readiness in your browser.

Mirown Image DPI Checker helps you understand whether an image is suitable for printing. Upload one image or multiple images, and the tool shows DPI X and Y when metadata is available, plus width, height, file size, format, and print readiness status.

If DPI metadata is missing, Mirown lets you calculate DPI from print width. The formula is simple: DPI equals pixels divided by inches. For example, a 3000 pixel wide image printed at 10 inches is 300 DPI.

How to check image DPI

  1. Upload JPG, JPEG, PNG, or WebP images.
  2. Review metadata DPI when the file includes it.
  3. If DPI is missing, enter print width in inches or centimeters.
  4. Read the calculated DPI, pixel dimensions, file size, and format.
  5. Use the print readiness status to decide whether the image is ready for printing.

Print readiness guide

  • High quality: 300 DPI or higher, usually print ready.
  • Medium quality: 150 to 300 DPI, often acceptable depending on print size.
  • Low quality: below 150 DPI, usually not good for sharp print output.

Why DPI can be confusing

DPI is often stored as metadata, but many images do not include it. Pixel dimensions matter more than the label alone. A large image can print well at a reasonable size even if no DPI tag exists, while a small image may look blurry if printed too large.
