Sharing photos online often inadvertently exposes sensitive private personal information (PII)—including bystander faces, car license plates, home addresses, utility bills, and credit card numbers.

Drawing crude markup pen strokes on your phone often leaves underlying pixels semi-transparent and recoverable with brightness adjustments.

ILoveImages' Blur Face and Censor tool permanently recalculates pixel neighborhoods with true destructive Gaussian blur and heavy mosaic pixelation, ensuring redacted data cannot be reconstructed.
