Blur or pixelate faces in a photo, free in-browser face redactor

Photos of strangers come with a privacy bill that gets bigger every year. A school-event picture has the bystander parents, a real-estate listing has the neighbours, an OSINT investigation has the source. Most face-blur tools online run on someone else's server, which fixes the problem only by trusting a different stranger with the original image. This tool removes that trade. The face detector and the redaction step both run inside your browser; the image never leaves the page.

The Auto-redact button runs the detector on the source image and turns every face it finds into a redaction rectangle. The brush overlay lets you add rectangles by hand for license plates, name badges, tattoos, or any other identifying region the detector did not flag. Each rectangle uses the redaction style and strength you picked: pixelate (the default), blur, or black-box. Pixelate is hard to undo but not impossible; blur can sometimes be partly recovered with the right software, and the tool shows a warning when you pick it; black-box is the only truly unrecoverable style.

The output is a fresh PNG, written from scratch with no camera, location, or copyright tags. Source GPS coordinates and camera serial numbers do not leak into the result. There is no toggle for that; it is the privacy default.
