How do I blur a face in a photo?

Drop your photo onto the upload zone (or click to browse, or paste with Ctrl+V / Cmd+V), then drag a rectangle over each face you want to hide. Adjust the blur strength, press Export, and download. It is completely free and runs entirely in your browser, so your photo is never uploaded.

Are my photos uploaded to a server?

No. The blur is applied entirely in your browser; the photo never leaves your device. Because faces are sensitive, this on-device processing is the whole point.

Can I blur more than faces?

Yes. Drag a rectangle over anything you want to hide — license plates, house numbers, ID badges, signatures, or screen contents. Add as many regions as you need.

Is blur as safe as a black box?

A strong blur makes faces unrecognisable and looks more natural than a black box, but for guaranteed removal of text or numbers, use a very high strength, or use the Redact tool's blackout for an opaque cover.

Does it detect faces automatically?

Not yet — you draw the areas to blur, which is precise and reliable. Automatic on-device face detection is a planned enhancement.

Is the Face Blur tool free?

Yes — blurring faces, license plates, and other sensitive details in your photos is completely free, forever. No account, no sign-up, and no limit on how many images you blur. The gaussian blur is applied in your browser using the Canvas API; your photos are never uploaded to any server. The site is ad-supported.

Does it work offline?

Yes. The tool uses the Canvas API and needs no server connection, so it works offline after the page loads.

Blurring is applied only inside the rectangles you draw; the rest of the photo is untouched and exported at full resolution.
A gaussian blur of sufficient radius makes a face unrecognisable while keeping the surrounding image natural-looking.
For sensitive text or numbers, a higher blur strength (or an opaque blackout) is safer, since a light blur can sometimes be partially reconstructed.
The Canvas blur filter used here is specified by the W3C Filter Effects standard and supported in all modern browsers.
Because the blur runs client-side, the photo is never transmitted, keeping faces and personal details private.
