Blur Image
Blur parts of an image online for free — automatically detect faces, or drag over number plates, names, screens and documents, then blur, pixelate or black them out. Blur the whole image for backgrounds. Processed at full resolution, 100% in your browser.
100% private — your files never leave your browser. Conversion happens on your device; nothing is uploaded.
Face detection uses Google’s open-source MediaPipe model and runs on your device — it’s downloaded once (about 10 MB) the first time you use it. For sensitive information, choose Solid black: strong blur and pixelation are hard, but not impossible, to reverse. Your image never leaves your device.

How do I blur a face in a photo?
Drop the photo in and click “Detect faces” — each face gets an oval that's blurred automatically. Drag an oval to adjust it, or draw extra areas by hand.
How does face detection work?
Click “Detect faces” and Google's open-source MediaPipe face model finds faces on your device — nothing is sent to a server. It's downloaded once (about 10 MB). Small, side-on or covered faces can be missed (and animal faces are sometimes found too), so check the result and draw extra areas by hand.
Can blurred or pixelated areas be reversed?
Strong blur and pixelation are very hard to undo, but not impossible for small amounts of text. For passwords, ID numbers or anything sensitive, choose Solid black.
Are my photos uploaded?
No. Detection and blurring both run in your browser, so your photos never leave your device.
