Good to know

  • Passport photo: 35 × 45 mm. PAN photo: 3.5 × 2.5 cm at 200 DPI. Signature boxes are often 140 × 60 px. Always check the form's own instructions.
  • Set the unit to cm and the DPI the form mentions; the tool converts to the right pixel size for you.
  • Shrinking an image keeps it sharp; enlarging a small one beyond its original size will look soft.

Questions people ask

How do I convert cm to pixels?

Will resizing make my photo blurry?

Making it smaller keeps it sharp. Enlarging beyond the original adds blur.
