NZ Passport Photo Checker

This tool analyzes an uploaded portrait image to determine if it conforms to New Zealand passport photo standards. It evaluates background uniformity, face size, head position, expression, lighting, and cropping, producing a clear report that highlights issues and suggests fixes. It employs computer vision to estimate a face bounding box, tilt, and crop margins, and it checks brightness and shadows to ensure consistent, noise-free capture. The analysis is aligned with ICAO guidelines, adapted for NZ requirements, and outputs a structured pass/fail result with actionable recommendations. Users such as applicants and professional photographers can leverage the report to adjust framing, recapture when necessary, and revalidate before final submission. The tool supports batch processing for multiple images and provides an exportable summary suitable for records or client handoffs.
