FAQ
Questions, answered
Does changing DPI change how the photo looks on screen?Open
Metadata-only mode does not change pixels. Resample mode changes pixel count so the printed centimetres stay the same at the new DPI.
Which DPI do Indian forms want?Open
200 or 300 DPI is typical for passport and Aadhaar prints. Screens are 72 or 96.
