About This Passport Photo Page
A passport photo size checker helps catch technical upload problems before submission. Enter the pixel dimensions, file-size range, and format displayed by your application portal, then choose your photo. The checker reads the image locally and compares its dimensions, aspect ratio, bytes, and file format with those values. It also samples the outer corners to provide background guidance. That background result is only a visual prompt: software cannot confirm identity-photo compliance, face position, recency, lighting, or acceptance by an authority. Requirements vary by country, document, application type, and portal, so always use the current instructions for the form you are completing.
