Why 413 × 531 pixels?

Those pixel dimensions correspond to a 35 × 45 mm photo at 300 DPI, the proportions commonly used for Indian and European document photos. Requirements differ between enrolment centres and online forms, so check what your form asks for.

What if my file is still over 50 KB?

The tool reduces dimensions before it reduces quality, so the result stays as sharp as the limit allows. If it cannot reach the target it says so rather than producing something unusable.
