Blur as many faces in as many photos as you need. No registration, no watermarks on output.
Frequently Asked Questions
Does it detect all faces automatically?
Yes — the AI detects all visible faces in the image and blurs them simultaneously. In rare cases, partially obscured faces, very small faces, or unusual angles may not be detected. You can manually select and blur any missed areas.
Can I control how strong the blur is?
Yes. Adjust the blur strength from a light obscuring effect to a heavy pixelated block that makes faces completely unrecognizable. For social media, a moderate blur is usually sufficient. For full anonymity, use the strongest setting.
Is my photo uploaded to detect faces?
No. Face detection runs entirely in your browser using on-device machine learning. Your photos are never sent to any server, which is especially important given that face data is biometric and highly personal.
