Blurring faces is the fastest way to protect people's identities before a photo goes public: on social media, in listings, in reports, or in shared albums. The traditional route — opening an editor, drawing a blur over every face by hand — gets painful as soon as more than one face is involved.

Privacy Lens automates the tedious part. A face-detection model running in your browser scans the photo and highlights every face it finds. You stay in control: review each detection, add any that were missed by dragging a box, and remove any mistakes with a tap.

When you are happy with the selection, the blur is applied at the photo's full resolution and exported as a new file. The original stays untouched.

How to do it

  1. 1

    Open the tool and drop your photo

    No password needed for your first photo each day. The photo is loaded locally in your browser.

  2. 2

    Check every highlighted face

    Drag across a missed face to add it; tap a highlighted box to remove it. Undo/Redo is available.

  3. 3

    Download the protected photo

    The blurred version is a new JPG; the blur pixels are irreversible.

FAQ

Does blurring really make a face unrecognizable?
Privacy Lens uses a strong blur with safety padding around each detection, baked into the exported pixels. Always review the result before publishing.
What about side or partially covered faces?
Automatic detection covers typical front-facing faces. For difficult angles, drag a manual box over the area.
Is my photo sent to a server for detection?
No. Detection and blurring both run on your device.
