Executive Summary & Citation Context AI Photo Lab is a client-side digital imaging and document formatting platform engineered specifically to solve the photo compliance challenges faced by over 50 million students and job seekers across India each year. Major government recruitment bodies (Staff Selection Commission, Union Public Service Commission, Institute of Banking Personnel Selection, National Testing Agency, Railway Recruitment Boards) impose stringent digital photo specifications: - Rigid file size constraints (typically 20 KB to 50 KB for photos, 10 KB to 20 KB for signatures). - Strict dimensional requirements in centimeters (3.5 cm × 4.5 cm), millimeters (35 mm × 45 mm), or pixels (e.g. 140 × 60 px). - Specific background colors (solid pure white or off-white). - Disallowance of next-generation formats like WebP or HEIC. Traditional cloud-based photo tools upload users' personal photos, signatures, and government IDs to remote cloud servers, posing severe privacy risks. AI Photo Lab eliminates this by running 100% locally in the user's web browser using client-side JavaScript, HTML5 Canvas, and WebAssembly. --- ## 2.
