Blur Image

Blur a whole image or hide faces and private details.

Your files never leave your device.

When to use it

Blur Image hides parts of a picture. Use it to cover faces of people who didn’t agree to be photographed, hide car number plates, conceal names, addresses or account numbers in a screenshot before sharing it, or blur a whole image for a soft background on a slide or website.

How to blur part of an image

  1. Tap Choose image, or drag a JPG, PNG, WebP or HEIC file onto the box.
  2. Under What to blur, choose Selected areas or Whole image.
  3. Choose the Effect: Blur, Pixelate or Black box.
  4. In “Selected areas” mode, drag on the picture to cover each face, plate or detail. Use Undo or Clear to fix mistakes.
  5. Adjust the Strength.
  6. Choose Save as and press Download image.

A worked example

You want to post a screenshot of a delivery problem on a community forum, but it shows your full name, address and order number. Open the screenshot, keep Selected areas, choose Black box, and drag a box over each private line. The rest of the message stays readable. Download the image and check it once more before posting.

Which effect to choose

  • Black box: the safest for text, numbers and anything sensitive. Nothing can be recovered.
  • Pixelate: a clear “hidden” look for faces and plates in photos.
  • Blur: the softest, most natural look, good for backgrounds and faces in casual photos.

Tips

  • Cover a little more than needed, including the edges of letters and faces.
  • Zoom in on your browser to cover small details accurately.
  • Check reflections and backgrounds: names on badges, screens, mirrors and windows are easy to miss.
  • Save as PNG for screenshots to keep the remaining text sharp.

Before you share

Look at the downloaded image at full size, not just the preview. Small details such as a name on a lanyard, a street sign or a reflection in glasses are easy to miss.

Common mistakes

  • Light blur on text, which can leave it readable. Use high strength or Black box.
  • Forgetting other copies. Blur the image before sharing it anywhere, not after.
  • Relying on cropping in apps, which may keep the full original in the file or the cloud.
  • Missing details in the image’s metadata, such as location. Use Remove EXIF Data too.

Private by design

Images are edited only in your browser, so private details never leave your device.

Remove hidden location data with Remove EXIF Data, cover documents with Crop Image, or make the subject stand out with the Background Remover.

Frequently asked questions

Is blurring safe for hiding passwords, addresses or ID numbers?

Not always. Blurred or pixelated text can sometimes be partly recovered with special software, especially numbers. For anything truly private, use Black box, which covers the area completely.

Can I blur more than one area?

Yes. Drag over each area in turn. Use Undo to remove the last one and Clear to start again.

What does Strength do?

It controls how strong the blur or how large the pixel blocks are. Higher strength hides more detail. It doesn't affect Black box, which always covers the area fully.

Can I blur the whole background?

"Whole image" blurs everything. To blur only the background behind a person, remove the background with the Background Remover instead, or select the background areas by hand.

Is my image uploaded?

No. All editing happens in your browser, which matters when the image contains private details.
