    Blur a face by drawing the box yourself

    This blur face tool covers faces, number plates and name badges with boxes you draw on the photo yourself. There is no automatic face detection here, and that is a deliberate choice, explained further down this page. You drag a rectangle over each face, pick pixelate, blur or solid fill, set the strength and how far the box pads out past the edges, and download a copy with the faces covered. One photo at a time, so each picture gets a proper look before it leaves your hands.

    Pixelate is the starting setting and the recommended one. It replaces each block inside the box with its average color, which breaks up the features a face is recognized by. Blur smooths those features instead, and solid fill removes them outright.

    How to blur faces in a photo

    1. Add one photo to the box above.
    2. Drag on the photo to draw a box over the first face. Make it a little bigger than the face itself, chin to hairline and ear to ear.
    3. Choose the effect. Pixelate is the default for a reason, blur looks softer, and solid fill hides the most.
    4. Set the strength and the padding, then draw boxes over every other face, plate or badge in the shot.
    5. Zoom in and check the whole photo once, corners included, then download the covered copy.

    Why you draw the boxes, not a detector

    Automatic face detection sounds easier, and it fails in quiet ways. Detectors miss faces in profile, faces turned partly away, small faces at the back of a group, and faces in shadow or behind sunglasses. A tool that claims it found every face invites you to share the photo without looking, and one missed face stays fully visible in the shared copy. When you draw the boxes, you have looked at every person in the frame, which is the check that actually protects people.

    Manual boxes also catch the things detectors ignore: number plates, name badges, house numbers, school logos on uniforms, and faces reflected in windows or mirrors. If a photo needs whole-frame softening or regions on objects instead, the blur image tool covers that on its own page.

    Which effect hides a face best

    Of the three, plain Gaussian blur is the weakest cover. Research on deblurring has recovered surprising detail from blurred faces, and face recognition software can work with less detail than a human eye needs. Pixelate with generous blocks is stronger, because whole features collapse into single colors. Solid fill is the strongest of all, since the pixels are replaced rather than disguised.

    Even the strongest fill has a limit worth stating plainly. No effect on this page guarantees anonymity. Clothing, location, companions and the photo caption can identify a person whose face is perfectly covered. Cover the face because it helps, and think about the rest of the frame before you post. The wider image tools category has the related editors and converters.

    Your photos stay on your device

    Photos of children, students, patients and customers should not be uploaded to a random server for a ten-second edit. Here nothing is uploaded at all. The photo is read, covered and saved inside your browser tab, and no copy exists anywhere else.

    FAQs

    Does this tool find faces automatically?

    No. You draw each box yourself. Automatic detectors miss faces in profile, in shadow and at the back of groups, and a missed face stays visible. Drawing the boxes means a person has checked the photo.

    Which effect should I pick for a child’s face?

    Pixelate with large blocks, or solid fill. Both hide far more than blur. Add padding so the box covers hair and chin, and check the result at full size before sharing.

    Can someone remove the blur and see the face?

    Blur is the easiest of the three to attack, and deblurring research keeps improving. Pixelate is harder to reverse, and solid fill cannot be reversed at all, because the original pixels are gone from the copy.

    Can I blur a number plate with this?

    Yes. Draw the box over the plate the same way you would over a face. Solid fill or strong pixelate keeps the characters unreadable, and the padding setting covers the plate edges.

    How many boxes can I add to one photo?

    As many as the photo needs. Group photos often need one box per person, plus extra boxes for plates, badges or reflections. Each box uses the effect and strength set for the photo.

    Will the covered photo look different in quality?

    Only inside the boxes. The rest of the photo keeps its original pixels and sharpness, and the download is a fresh copy, so your untouched original stays as it was.
