What this tool does

Check pixel dimensions and print density. Changing the DPI tag changes the suggested printed size, not the amount of photographed detail.

One still image, up to 25 MB, 50 megapixels and 16,000 pixels per side. Animated/multipage inputs use the first frame. Files use the existing upload checks, virus scan, queue and automatic deletion.

  1. 1

    Choose the source image and inspect its current density.

  2. 2

    Choose Check DPI or enter a new print density.

  3. 3

    Compare pixel dimensions to confirm they did not increase.

Files are processed in India, virus-scanned, and deleted automatically after one hour.

Common questions

Does 300 DPI make a small photo sharper?

No. A density tag cannot recover missing pixels or detail.

Why is DPI sometimes unknown?

Many web images have no physical-density units. The viewer reports unknown instead of claiming 72 or 96 DPI as a fact.

How are centimetres converted?

Pixels per centimetre are multiplied by 2.54 to report pixels per inch.
