Blur a Photo, or Just the Part That Matters

Open a photo and it is softened straight away: one slider says how much, and Whole picture is where the tool starts. That is the blurred background, the frosted look behind text, the photo that has to suggest a scene without showing it. Images of any size are handled the same way, from a phone screenshot to a 40 megapixel photograph.

The other half of the job is hiding one thing rather than everything: a face, a child, a name badge, a number plate, an address in a screenshot. Switch to Areas and drag a box across whatever should not be readable. The area is blurred as soon as you release, you can move it, resize it or add more, and the download is your original picture at full resolution with the blur burned in. Nothing is uploaded, there is no signup and no watermark.

Blur or Mosaic

Two ways to cover something, and they hide differently.

Strength drives both: it sets how far the blur reaches and how large the mosaic squares are. Both are measured against the picture's own size, so the preview shows exactly what the downloaded file will look like, whether the photo is from a phone or a 40 megapixel camera.

Areas Are Rectangles or Ovals

Drag anywhere on the picture to make an area. Drag inside one to move it, pull its corner to resize, and use the cross in its corner to remove it. Add as many as the picture needs; a group photo with four faces takes four drags. Undo steps back through all of it.

Ovals suit faces and heads, rectangles suit signs, labels, plates and blocks of text in a screenshot. The picker changes the area you have selected and sets the shape for the next one you draw, so a picture can carry both.

Covering Something Properly

A cover only works if what is under it cannot be reconstructed, and a light blur over small text can still be readable. Two habits are worth having.

Turn the strength up until you cannot tell what was there, then a little further. A face needs more blur than most people give it, and the test is whether you would recognise the person, not whether the area looks smudged. For text, mosaic with large squares is safer than a gentle blur.

Cover a little more than the thing itself. Hair, an ear or the edge of a badge outside the box gives back more than you would think, so drag the area wider than the face and past the ends of a plate or a name.

Where This Gets Used

Faces of children and bystanders in pictures that are going online, number plates in a car advert, house numbers and street signs, names and addresses in a screenshot of an email or a document, account numbers on a receipt, a face in a dating or marketplace listing, and a background blurred to keep the eye on the subject.

If you want to blur only the edges of a picture instead, Feather Edges fades them out; Highlighter Tool marks something instead of hiding it, and Add Emoji can cover a face with a sticker rather than a blur. The site carries hundreds of other image utilities besides these; see what is live right now on the all tools page.

Frequently Asked Questions

How do I blur part of an image?

Open the picture and drag a box over the part you want hidden. It is the same gesture for pics from a phone and for scanned pictures. That area is blurred as soon as you release, and you can move it, resize it from the corner or add more areas. Press Download when the picture is covered the way you want.

How do I blur a face?

Drag an area over the face, choose Oval if you want the cover to follow the head, and turn the strength up until you would not recognise the person. Cover a little more than the face itself, because hair and the shape of an ear give away more than people expect.

Blur or mosaic, which hides better?

Mosaic with large squares is the safer of the two for text and numbers, because nothing of the letter shapes survives. For a face, a strong blur usually looks better and hides just as well. What matters in both cases is the strength: a light cover of either kind can still be read.

Can I blur the whole picture?

Yes. Switch to Whole picture and the strength slider softens everything, for a blurred background or a frosted panel behind text.

Does the download lose quality?

No. The blur is applied to your original picture at its true size, not to the smaller preview on screen, so the parts you did not cover stay exactly as sharp as they were. Save as PNG to keep transparency, or JPG and WebP for a smaller file.

Is my photo uploaded anywhere?

No, and for this tool in particular that matters. The picture is opened, blurred and saved on your own device. Nothing is sent to a server, so the thing you are hiding never leaves your computer.
