How do I blur a face in a photo online for free?

Upload your photo above, drag the blur blob over the face, set the strength to 25px or higher, and click Download. It's free, runs in your browser, and needs no sign-up.

Is my photo private and secure?

Yes. Face placement, the blur and the final export all run in your browser using the Canvas API — your photo never leaves your device and nothing is sent to a server.

What image formats are supported?

JPG, PNG, WebP, GIF, AVIF, and BMP are accepted on upload. The blurred result is exported as a PNG to preserve quality.

Can the blur be reversed?

At 25–40px strength on a typical face, the blur is irreversible — the exported PNG has no hidden layer or metadata. Use the Verify step to zoom to 100% and confirm before sharing.

Can I blur multiple faces?

Yes. Click Add blob to drop another blur over each face, or use a larger blob to cover a group.

How do I hide a face with a shadow instead of blurring it?

Switch the effect to Shadow. It lays a black-to-transparent gradient over the face — pick the direction the shadow falls and dial the darkness up until the features disappear. It reads as a face hidden behind shadow, not a censor block.

Does it work on my phone?

Yes. The tool is browser-based and works on modern iPhones, Android phones, and tablets — drag with one finger and pinch the corners to resize.

How to blur a face in a photo

Upload your photo

Drag it onto the tool or click Upload Image. It's private, secure and runs entirely in your browser — your photo never leaves your device. JPG, PNG, WebP, GIF, AVIF and BMP are accepted.

Blur the face

A feathered ellipse is dropped on the canvas by default. Drag it over the face, use the Size and Rotation sliders to fit it, and pick Blur, Pixelate, Cover or Shadow. Add more blobs for multiple faces.

Verify & download

Hit Verify to zoom to 100% and confirm the face is unrecognizable, then click Download. You get the same image back at the exact size you uploaded, as a flattened PNG with EXIF and metadata stripped.

Blur, pixelate, cover or shadow

All four hide a face, but they read differently. Pick the one that fits the photo and the reason you're hiding the face.

🌫️

Blur

A soft Gaussian smear that blends into the image — keeps the photo looking natural. Best for aesthetics.

Pixelate

Breaks the face into blocky mosaic cells — the classic censor look. At a small enough cell size it's just as hard to reverse.

Classic censor

⬛

Cover

A solid black box — the strongest redaction. Use it for sensitive contexts: minors, witnesses, IDs.

Strongest

🌑

Shadow

A black-to-transparent gradient that hides the face behind a cast shadow — anonymous without looking redacted.

Hide face

Hide a face with a shadow gradient

Sometimes you don't want a blur or a censor block — you want the face to read as hidden behind shadow, the way a face falls into darkness in a moody portrait. The Shadow effect lays a black-to-transparent gradient over the face instead of pixelating it.

Why blur your face in a profile picture

🔒

100% private

Detection, blob placement and the final blur all run in your browser. Your photo never leaves your device.

🚫

No signup

No email, no account, no watermark. Open the page, upload, and download — that's the whole flow.

🖼️

Original-size export

You get the same image back at the exact size you uploaded — no resizing, no presets, no quality loss. The blur is baked in and EXIF is stripped.

✅

Verify before share

A built-in zoom-to-100% check so you confirm the face is unrecognizable before you download and share.

🔒

Is the blur irreversible?

A Gaussian blur at 25–40px on a typical face destroys the pixel information — there's no hidden layer and no adjustable mask in the exported file, so it can't be walked back with sharpening or upscalers. Our export also strips EXIF and metadata, so your location and device details don't travel with the photo. Always zoom to 100% and confirm the face is fully obscured before you share — that's what the Verify step is for.
