How to Check if an Image Is 300 DPI
Use the checker to read the image’s embedded X and Y resolution. A result near 300 DPI means the file carries that metadata; it does not guarantee sharpness, correct color, or a suitable print size. If the result says Not specified, the file has no reliable resolution label.

Print reality check
Will it work at your print size?
Pixel dimensions—not a metadata label—determine usable print detail.
Choose an image, then check a print size.
Look for the metadata, then check the pixels
Resolution metadata is a setting associated with the file. Pixel dimensions are the actual width and height of the image data. For example, a 3000-pixel-wide image can provide 10 inches at 300 DPI, regardless of whether a file viewer displays a different label.
300 is a common target, not a universal rule
300 DPI is a useful target for many close-viewed photo prints, but it is not a general pass/fail quality guarantee. Large signs are viewed farther away and may use a lower effective DPI. Small text, line art, a poor original capture, or heavy compression can look bad at 300 DPI.
If it is not exactly 300
Ask the receiving printer or publisher for its specification. If the pixels are sufficient and only the metadata label is wrong, the metadata converter can create a 300 DPI copy for supported formats. It changes resolution metadata; it does not add pixels or restore detail.
