Face Blur
Proposes face boxes from a skin-colour heuristic — no model, so it also finds hands and misses shaded faces — for you to confirm or draw over, then mosaics them by rewriting the pixels.
The candidates on this page come from a published skin-colour rule, not face recognition — so it proposes hands, arms and peach-coloured walls, and misses faces in shadow or in profile. Nothing is redacted until you confirm a box, which is why the page is built this way round.
Drop the photo to redact
Faces are proposed from skin colour. The photo is not uploaded, and redacted pixels are gone from the file.
How to use it
Drop the photo and read the proposals
They arrive as dashed boxes with a score. The score is how face-shaped the blob is, not a probability.
Confirm the ones that are faces
Click a box to accept it and click again to release it. Nothing is redacted while a box is still dashed.
Drag in what it missed
A face in profile, a number plate, a name badge — drag on the photo and the region joins the list.
Redact and export
The pixels are rewritten and the file encoded from that buffer — the same guarantee the redaction tool makes, because it is the same code.
Common questions
Why does it not detect faces properly?
Because it is not a detector. It finds blobs inside a skin-colour range (YCbCr) and keeps the face-shaped ones. A real detector means downloading a model; this works instantly on any device and is honest about what that costs.
It found nothing in a photo full of people.
If much of the frame falls inside the skin-colour range — sand, wood, a peach wall — there is nothing for the rule to separate, and the page says so. Drag the regions in by hand.
Is the photo uploaded to check the faces?
No. Nothing is uploaded and no model is downloaded — the whole thing is arithmetic in this tab, which is also why it works with no network.
