Tool Photo Scrubber — local face blur & metadata removal — View and edit photos locally to blur faces and remove metadata before sharing. The tool automatically detects faces using machine learning, allows manual redaction with adjustable blur strength, and exports cleaned images with all personal metadata stripped. All processing occurs in the browser—photos never leave your device.
I took a photograph of some protesters, then thought about how I don't like sharing photographs of strangers with identifiable faces. I had GPT-6 Astra build this experimental tool that would identify faces and automatically blur them out.
It uses Google's MediaPipe C++ library, compiled to WebAssembly via @mediapipe/tasks-vision, plus the BlazeFace face detection model.
