UPSC photo, 20–300 KB
Use a recent colour photo on a plain light background. Crop square so the face covers about three quarters of the picture and both ears show.
UPSC also takes a live photo on the application. This file does not replace that capture.
What usually goes wrong
A small face in a large background is the usual miss. Look straight at the camera. No cap.
