The tool uses client-side OpenCV WebAssembly and bilateral filtering algorithms to detect facial feature edges (eyes, lips, hair), sharpen high-frequency details, and remove pixel noise caused by WhatsApp compression.
Super-resolution upscaling doubles (2x) or quadruples (4x) the pixel dimensions of your photo using bicubic interpolation and edge sharpening, making small passport snapshots crisp enough for 300 DPI physical photo printing.
The 'Studio Light' preset is optimal for passport photos because it balances skin tones, removes harsh ambient room shadows, and produces a clean, professional studio lighting effect.
Yes. Click the 'Print Sheet (4x6)' button to automatically format your enhanced portrait into a standard 8-photo 4x6 inch grid layout with cutting guides ready for immediate printing.
No. All AI sharpening, color grading, upscaling, and sheet generation occur 100% locally inside your web browser using WebAssembly. Your photos never leave your device.
