Frequently asked questions
Are my images uploaded?
No. ImgShrink processes selected images in your browser and does not upload them to a server.
Which DPI should I use?
300 DPI is a common high-quality print target, 150 DPI can work for general print, and 72 or 96 DPI is mainly screen-oriented.
Is this a final print or document approval check?
No. The calculator gives pixel, DPI and physical-size math. Printers, passport offices and upload portals may apply extra rules.
Source and compatibility notes
DPI and print-size results use standard pixel-to-physical-size formulas. Document-photo presets are reference sizes, not a substitute for official submission rules.
