One click finds the faces and blurs them all; a strength slider and a pixelate-or-smooth-blur choice control the look.
Blur Faces in Photos Online - Private, On-Device
Blur or pixelate every face in a photo before you share it. The face blur tool on this page runs entirely in your browser: the picture is opened on your device, analyzed on your device, and blurred on your device - it is never uploaded anywhere.
The one-click path does the common job. Choose a photo, press the blur-all-faces button, and the tool finds each face and covers it. The first press starts a one-time download of the face detector - a small on-device model of about 1.3 MB, with the size stated on the button before you commit - and your browser caches it, so later photos skip the download entirely. From there the detector runs locally in a fraction of a second and marks every face it finds with better than 70 percent confidence.
Two controls shape the result. The style choice switches between pixelate, the classic mosaic-block look, and a smooth blur that melts the region into soft color. The strength slider scales how coarse the blocks or how wide the blur radius gets, so a face can be lightly softened or made completely unreadable. Whichever you pick, the effect is applied on the full-resolution picture: everything outside the blurred regions stays pixel-for-pixel identical to your original.
The brush handles everything the detector cannot. A face detector finds faces - it does not find licence plates, tattoos, name tags, or house numbers, and a very small, turned-away, or partly covered face can slip under its confidence bar. Paint over any of those with the adjustable brush and press the no-download blur button: the painted area is blurred instantly, with no model fetch and no network use at all. That same button is the full fallback path - if you would rather not download anything, or the detector cannot load, the brush alone still finishes the job.
When you are done, the result saves as a PNG re-encoded from the canvas. Re-encoding means the original photo file's hidden metadata does not travel into the output - what you download is the pixels you see, nothing more. A real before-and-after example is already rendered above, produced by the same detector this page uses on a public-domain portrait, so you can see the output shape before choosing a photo of your own.
One honest boundary: blurring hides a face, it does not certify anonymity. Heavy pixelation resists casual recognition, but clothing, location, and whatever you write alongside the photo can still identify a person - review the whole picture before you post it. And when the goal is to make someone or something disappear from the scene entirely rather than hide it, the object remover erases the painted region and fills in matching background instead.
Frequently Asked Questions
Is my photo uploaded to a server?
No. The photo is opened, analyzed, and blurred entirely in your browser - it never leaves your device. The only thing that ever downloads is the face detector itself, about 1.3 MB, one time, and only after you click the AI button.
What happens if the tool misses a face?
Small, turned-away, or partly covered faces can slip under the detector's 70 percent confidence bar. Paint over the missed face with the brush and press the no-download blur button - the painted area is blurred instantly, with no network use at all.
Can it blur licence plates or tattoos automatically?
No - the on-device model detects faces only. Plates, tattoos, name tags, and house numbers are exactly what the brush is for: paint the area by hand and blur it with the no-download button.
Should I pick pixelate or smooth blur?
Pixelate gives the classic mosaic-block look and, at higher strength, is the harder of the two to reverse-read. Smooth blur looks softer and less conspicuous in a photo you still want to look natural. The strength slider scales either one, so preview both on your picture before downloading.
Does the downloaded picture keep the original photo's hidden metadata?
No. The result is a PNG re-encoded from the canvas, so the original file's embedded metadata is not carried over - the download contains the pixels you see and nothing more.
Is a blurred face guaranteed to be anonymous?
Blurring hides the face; it does not certify anonymity. Clothing, location, and the text you post alongside a photo can still identify someone, so review the whole picture before sharing. To remove a person from the scene entirely instead of hiding the face, use the object remover tool on this site.
