A little clarity for every image

DPI Checker

Check the DPI of an image online. View its pixel dimensions, file size and resolution metadata, including missing or conflicting DPI values.

Read the file. Keep the detail.

See both DPI axes, actual pixels and every available resolution source. Missing or conflicting metadata is shown explicitly.

Need to know how this image will print?

Results are kept in this browser for up to 24 hours.

Read the resolution recorded in your image, including horizontal and vertical values, metadata sources and missing or conflicting fields.

Read the file before changing it

  1. Choose the original supported image rather than a screenshot of it.
  2. Read pixel width and height, both resolution axes and each reported source.
  3. Open the detailed result. Compare the available pixels with your intended print dimensions before deciding whether to change a label or resize.

What the reported DPI means

A 300 DPI label indicates an intended density; it is not a quality certificate. A 600 × 600 image at 300 PPI corresponds to a 2 × 2 inch print. At 6 × 6 inches the same pixels provide only 100 PPI.

Not specified means no usable physical density was found. Conflicting means the file contains values that disagree. Different applications can select different fields, so the detailed report keeps sources visible instead of hiding the disagreement.

Choose your next action

If the pixels meet your target and the label is wrong, use DPI Converter. If the intended print is too large, choose a smaller print or find a larger original. Use Resizer only when you intend to change pixels, not as a way to make missing detail reappear.

Frequently asked questions

Is 72 DPI necessarily low quality?

No. Inspect the pixel dimensions and desired physical size. A large image can have a 72 DPI label and still contain enough pixels for a detailed small print.

Why are there two DPI values?

Horizontal and vertical density can be recorded independently. Check both axes, particularly when the file contains conflicting metadata.

Can a missing DPI value be calculated from pixels alone?

Not uniquely. You also need an intended physical size or a chosen density.

Can I check 300 DPI?

Read both axes and compare them with 300, allowing for format storage rounding. Then check the print-size requirement separately.
