Why recruitment commissions prescribe DPI and physical dimensions instead of just pixel counts.
Since 1 inch = 2.54 cm = 25.4 mm, DPI directly links the virtual pixel world to the physical print world.

DPI (Dots Per Inch) refers to physical printing or scanning density, while PPI (Pixels Per Inch) refers to digital display density. In digital exam forms, both terms are used interchangeably to indicate how many pixels make up one inch of the image.
If the portal strictly validates DPI metadata, the upload will be rejected with an error like "Resolution must be 200 DPI". Using our Photo Resizer tool automatically encodes the official 200 DPI metadata header into the output JPEG file.
Locking the aspect ratio ensures your photo never appears stretched, squashed, or distorted when modifying either width or height.
