FAQ

Is my image uploaded anywhere?
No. The DPI change happens entirely in your browser using JavaScript — your image never leaves your device.
Will changing the DPI make my image blurry or resize it?
No. DPI only controls how large the image prints — the pixel dimensions and image quality are completely unchanged.
What DPI should I use?
72 DPI is standard for screens and web, 150 DPI works for everyday printing, and 300 DPI is the usual minimum for high-quality print and photo labs.
