DPI Converter — Make Any Image Print-Ready (300 DPI)
Print shops and government portals reject images for the wrong resolution, not the wrong file. Set the physical size (inches or cm) and target DPI — 300 for print, 72 for web — and the tool resamples your photo to the exact pixel dimensions, centered on white, and downloads it as PNG. All in-browser.

DPI Is Just a Label — Under the Hood
A digital image only has pixels; DPI is metadata telling a printer how densely to place them. A 1050×1350 px photo is "300 DPI" at 3.5×4.5 inches or "150 DPI" at 7×9. The reliable move is computing target pixels = physical size × DPI and resampling once with high-quality interpolation — exactly what this tool does.
