Check the DPI of any image online

Before you change the DPI of an image, it helps to know which value is stored in it right now. This free DPI checker reads the metadata header of your JPG or PNG and reports the exact horizontal and vertical DPI — the same numbers a print shop's preflight software or a submission portal would see. It also shows pixel dimensions and the physical print size those pixels produce at the stored DPI, so you can judge at a glance whether a file is print-ready.

Checking DPI online is useful when a printer rejects your file, when you are preparing stock-agency submissions, or when you simply want to verify that a previous conversion worked. Because the analysis runs entirely in your browser, you can inspect sensitive or client photos without uploading them anywhere.

If the result shows “No DPI tag”, nothing is broken — screenshots, WEBP files, and many exported images simply don't carry one. Stamp in the value you need with the free DPI converter, then re-check here to confirm it stuck.

What this checker tells you

Every JPEG and PNG can carry a DPI value in its file header — JFIF or EXIF data for JPEGs, the pHYs chunk for PNGs. This tool reads that header directly, so you see the exact number a printer or submission portal would see. It also reports pixel dimensions and the physical print size the image would produce at its stored DPI.

No DPI tag found? That is normal for screenshots, WEBP images, and files exported from many apps. It simply means no print size was recorded — the pixels are unaffected. Use the DPI converter to stamp one in.

Common DPI values explained

  • 72 DPI — legacy screen value; pixel dimensions are all that matter on displays.
  • 150 DPI — common for large-format posters and banners viewed from a distance.
  • 300 DPI — the standard most print shops, photo books, and stock agencies require.
  • 600 DPI — high-end or fine-art printing.
