Infant & Child Photo Guidance

Taking Baby Passport Photos at Home Made Easy

Taking infant photos at retail studios is stressful and frequently rejected. PhotoResizer.us gives you unlimited retakes from home, automatically isolates your baby from the background, and applies relaxed government infant tolerances.

Lay Baby on a White Sheet

Place your baby on their back on a plain white blanket or sheet with no pillows or toys visible.

Capture Directly from Above

Hold your phone parallel to your baby's face from 3–4 feet away so both ears and eyes are level.

Relaxed Eye & Mouth Rules for Infants

Embassies allow infants under 1 year to have their mouths slightly open and eyes not looking directly forward.

No Hands or Parents in Frame

Ensure no parent hands, support pillows, pacifiers, or hats are visible in the photo crop.
