Quick Tool Overview

The Face Blur Tool uses the browser's native face detection where it exists and hand-drawn regions everywhere else — and it shows you what it found rather than assuming it found everything, because automatic detection always misses some. Blur and pixelation are both available with guidance on making either irreversible.

About the Face Blur Tool

Publishing a photograph with identifiable strangers in it is a consent problem in most of the world and a legal one in some of it. Blurring faces is the standard remedy and it needs to be done reliably, not approximately.

Where your browser provides face detection natively — Chrome and Edge do — it is used to find faces automatically. Everywhere else, and for everything detection misses, regions can be drawn by hand, which is the part that actually matters: automatic detection finds most faces and never all of them, so the tool shows you what it found and expects you to check. Blur and pixelation are both available, with the strength guidance that makes either genuinely irreversible.

Key features of the Face Blur Tool

Native detection where available

Chrome and Edge expose a face detector, which finds most faces automatically with no download.

Manual regions everywhere

Draw a box over anything detection missed — the step that makes the result actually reliable.

Shows what it found

Every detected face is outlined so you can verify rather than trust, which matters for a privacy tool.

Blur or pixelate

With strength guidance, because a light blur is reversible and a heavy one is not.

Nothing uploaded

Sending photographs of identifiable people to a server in order to anonymise them would defeat the purpose.

How to use the Face Blur Tool

  1. 1

    Load the photo

    Detection runs automatically where the browser supports it.

  2. 2

    Every detected face is outlined. Automatic detection always misses some.

  3. 3

    Draw any it missed

    Drag a box over each remaining face — this is the step that makes it reliable.

  4. 4

    Set the strength

    Heavy enough to be irreversible, then download.

Frequently asked questions

No. Automatic detection misses profiles, partial faces, small faces and anything unusual. That is why manual regions are here, and why the tool tells you to check rather than trusting it.
