Blur People and Objects in a Photo Automatically

Detect people, faces, plates and screens with an object-detection model in your browser, then blur or black them out.

This tool runs an object-detection model in your browser to find people, vehicles and screens in a photograph, then blurs, pixelates or blacks out each detected region. The detection and the editing both happen on your device, which matters for redaction specifically — a tool that uploads the image you are trying to anonymise has already defeated the purpose.

Frequently asked questions

Is this good enough for compliance?

Check every result. Object detection misses people who are partly occluded, small in frame, or unusually posed, and a single miss defeats the redaction entirely. Use a low confidence threshold — over-redacting is the safe error — and review the output before publishing.

Can the blur be reversed?

Not from the exported PNG: the pixels are genuinely destroyed and re-encoded, not overlaid. That is the difference between this and drawing a black rectangle in a PDF or a layered editor, where the original data is still in the file.

Why does it not detect faces specifically?

The model here detects whole people rather than faces, which for redaction is usually the stronger choice — a person is identifiable from clothing, posture and context, not only their face.
