About Censor & Blur

Draw rectangles over sensitive items to blur, pixelate, or color-fill details. Perfect for passports, bills, and faces.

Resizing and moving are supported: select any drawn zone, drag corner handles to resize, or drag its center to reposition.

All redact zones are drawn directly onto the image's raw pixels before download, making it 100% irreversible.

Everything runs on your device. Zero bytes are uploaded to a server.
