Passport photo size in pixels
The single photo is made at 300 dpi, which is the usual print resolution. That means a 35 × 45 mm photo comes out at 413 × 531 pixels, and a 2 × 2 inch photo comes out at 600 × 600 pixels. If an online form asks for a digital photo, upload this JPG. If it also sets a limit in KB, run the JPG through Photo to KB afterwards.
CNIC, visa and ID card photos: what to check first
Each office sets its own rules for size, background, head size, glasses and expression, and those rules change. The size list names countries that commonly use each size, but treat it as a starting point. Always check the official website of the office you are applying to, whether it is for a CNIC, a passport, a US visa photo 2x2, a school ID card or a job form.
A few habits help with almost any office: face the camera straight on, keep a neutral expression, avoid shadows behind you, and take the photo in daylight near a window rather than under a single ceiling bulb.
Problems and privacy
If you see a message that the photo would print blurry, you have zoomed in too far for the number of pixels in your photo. Zoom out a little or start from a sharper, closer photo. If the white background has rough edges around hair, retake the photo against a plainer wall so the face stands out more.
The crop happens in your browser. For a white or light blue background, an AI model also runs in your browser. The first time it loads takes a few seconds, but your photo itself is never uploaded.
