About Face Blur Tool
Face Blur Tool blurs faces in a photo to protect people's privacy before you post or share it. Mark each face with a box, choose how strong the blur is and whether it is an oval or a rectangle, and download the result. The blurred area in the download is exactly the area you see marked on screen.
Automatic detection uses the browser's built-in face detector, which only some browsers provide, so on most desktop browsers you will mark faces by hand. Everything runs on your device and the photo is never uploaded.

Frequently asked questions
Why can't it find faces automatically?
Automatic detection relies on a face detector built into the browser, and most desktop browsers do not include one yet. Marking faces by hand works everywhere.
How strong should the blur be?
Strong enough that nobody could recognise the person. Raise the blur slider until the face is unreadable, and check the preview — it matches the download exactly.
Can a blur be undone?
Not from the downloaded file: the blur replaces the original pixels. Keep your original photo if you might need it later.
Is Face Blur Tool free to use?
Yes, Face Blur Tool is completely free with no usage limits, no watermarks and no sign-up required.
