Face Blur
Detect every face in a photo and blur it — runs entirely on your device.
About Face Blur
Face Blur finds every face in a photo and blurs it automatically, so you can anonymize people before posting or sharing an image. Detection and blurring run entirely on your device — the photo is never uploaded, which matters when the whole point is privacy. The result is a PNG with the faces obscured.

Frequently asked questions
Does my photo get uploaded to detect faces?
No. Face detection and blurring happen entirely in your browser on your device. The image never leaves your machine — which is the whole point for a privacy tool.
What image formats are supported?
JPEG, PNG, and WebP go in; the blurred result comes out as a PNG.
Will it catch every face?
It detects and blurs each face it finds, but very small, turned-away, or heavily obscured faces can be missed. Review the output before sharing anything sensitive.
Can the blur be reversed?
The blur is baked into the output pixels, so it can't be cleanly undone from the saved PNG. Keep your original separately if you need it.
Does it work offline?
Since processing is local, once the page is loaded it works without sending anything over the network.
