Indian passport photo, 630×810
Passport Seva asks for a colour photo of 630×810 pixels, face about 80 to 85 percent of the frame, plain light background, under about 250 KB.
The same instructions say the photo should not be altered in software. This page only crops and resizes. It does not replace the background.
What usually goes wrong
Both ears visible, eyes open, no smile, no heavy shadow. Religious headwear must still show the face from chin to forehead.
