DV Lottery Photo Editor

DV Lottery Photo Editor is a back-end image processing tool that accepts a user photo and returns a ready-to-submit image meeting U.S. Diversity Visa specifications. It analyzes image dimensions, color space, facial position, and background to determine eligibility and applies automated cropping and background correction. The tool is designed for DV lottery applicants, immigration consultants, and photo labs seeking reliable, standards-aligned results without manual trial and error.
Conceptually, the tool crops to center the head within a 600x600 canvas so the head height occupies 50-69% of image height, with eyes placed near the upper third. Background whitening replaces non-white areas with a pure white background while preserving natural skin tones. A brightness and color balance pass ensures neutral lighting and consistent skin tones across diverse lighting conditions.
Key features include strict input validation (JPEG/PNG, RGB, 600x600, no animations), automatic crop, background normalization, export in JPEG or PNG at 600x600 and 300 DPI, and a session-only processing log. The tool supports optional manual override for crop and brightness adjustments and provides a compliance note in metadata to aid verification.
Use cases cover self-submission by applicants, support staff in consulates, and photo labs seeking a repeatable process. What sets this tool apart is its explicit alignment with official criteria, automated decisions with audit-friendly metadata, and robust handling of edge cases such as multiple faces, poor lighting, or non-frontal poses.
