Image resolution usually means the number of pixels in a file. A photo measuring 4000 by 3000 pixels contains twelve million pixels, regardless of the PPI number written in its metadata. That distinction matters when sharing, cropping or printing.

What to do

  1. 1.Check the source width and height in pixels.
  2. 2.Choose the final display or print size.
  3. 3.Calculate whether the remaining pixels are adequate.
  4. 4.Export a separate copy without discarding the full original.

Start with pixel dimensions

Width and height determine the actual pixel information you have. Enlarging a small picture with software adds interpolated pixels, not lost camera detail. Inspect the original rather than trusting a “high resolution” label.

Understand print density

PPI expresses how many pixels are used per inch in a printed image. For example, a 3000-pixel-wide file at 300 PPI spans 10 inches; at 150 PPI it spans 20 inches. The pixels do not change, only the physical density.

Match output to use

A small website card needs fewer pixels than a large print. Crop first, then calculate the remaining pixel size. Ask a print service about its preferred dimensions because viewing distance and paper type affect what looks acceptably sharp.

Watch out for this

Changing a 72 PPI metadata field to 300 PPI does not create real detail.

Frequently asked question

Is DPI the same as image resolution?

Not exactly. DPI describes output dots in printing, while PPI describes image pixels per inch. For digital pictures, pixel dimensions are the main quantity to inspect.
