Image DPI Checker

It reads resolution metadata stored in a supported JPG or PNG and shows the image's pixel dimensions. The reported value is a file label used by some print and layout software, not a direct measurement of visible sharpness.

Some exports omit resolution fields because screens mainly use pixel dimensions. A missing value does not mean the image has no pixels or cannot print; it means physical size cannot be inferred from stored DPI alone.

Not by itself. A tiny image can be labeled with a very high DPI and still lack enough pixels for a large print. Judge print potential by combining pixel dimensions, intended physical size, and the printer's requirements.

Divide pixel width and height by the DPI value to estimate dimensions in inches. For example, the same file prints smaller at a higher DPI. Cropping, bleed, printer settings, and resampling can affect the final result.

No. The checker reads supported metadata and dimensions without rewriting the selected source file. If you choose to update the value afterward, that is a separate converter action that creates a new downloadable result.

Applications may read different metadata fields, apply defaults when fields are absent, or display document resolution instead of file metadata. Compare the original file and confirm which value the destination actually uses.

This checker supports JPG and PNG. Other formats can store resolution information differently or may not expose it through this workflow, so use a metadata inspector that explicitly lists support for the required format.

First confirm the destination's requirement and whether the image has enough pixels at the intended physical size. Then use the DPI converter to update metadata, or resize from a suitable source if more pixels are truly needed.
