Convert pixel dimensions to print size at a chosen DPI, or the reverse. Runs entirely in your browser — nothing is uploaded. For print orders, always confirm the service’s current file spec.
Rule of thumb: 300 DPI is common for close-up prints; large posters viewed from distance can work at lower DPI. “DPI” in print and “PPI” in image files are related but not identical; check your printer/POD service’s requirements. This tool does math only — it does not inspect or upload your files.
