What this does
Every image has real pixel dimensions, but "how big can I print this" depends on DPI too — pixels packed per inch. This reads your image's pixel size and any DPI value stored in the file, then lets you see the actual print size at any target DPI.
Reads real embedded DPI
Checks both EXIF resolution tags (common in camera photos) and the PNG pHYs chunk — not a guess.
300 DPI is the standard
For a sharp photo print, aim for 300 DPI. Lower works for drafts or large posters viewed from a distance.
Common questions
What is DPI?
How many pixels are packed into each printed inch — higher DPI means smaller, sharper prints.
What DPI do I need?
300 for sharp photo prints, 150 for drafts or large posters.
Why does my image have no DPI set?
Most web images and screenshots never had one saved — that's normal.
Does resizing change DPI?
No — DPI is metadata, not pixels. Printing bigger at the same quality needs more actual pixels.
