What is the standard resolution for passport photos?

Standard printing resolution is 300 DPI (dots per inch). For a 2x2 inch photo, this requires a minimum of 600x600 pixels.

Can I print multiple passport photos on a single 4x6 print?

Yes! ToolHero lets you export a standard 4x6 inch (1200x1800 px) photo sheet containing 2, 4, or 6 passport copies for printing at any pharmacy or photo kiosk.

Is my personal photo safe from being uploaded to third-party databases?

Yes. ToolHero operates 100% client-side. The image is cropped and compiled on your local device CPU and never transmitted over the internet.

Digital Passport & Visa Photo Specifications: DPI, Biometric Dimensions & Canvas Processing

International Biometric Standards for Travel Documents

Government immigration agencies and automated e-Gates (Automated Border Control systems) rely on sophisticated facial recognition algorithms. For automated facial matching software to map inter-pupillary distance, jawline contours, and nose-to-chin ratios, photos must conform to strict biometric constraints defined by the International Civil Aviation Organization (ICAO Doc 9303).

Comparison of Global Passport Photo Dimensions

Different geopolitical jurisdictions mandate specific physical dimensions and head proportions:
