What you can do here

Hide faces and plates

Blur children’s faces, bystanders, car number plates and house numbers before posting photos online.

Censor screenshots

Cover names, phone numbers, UPI IDs, OTPs and account details in chat or payment screenshots.

Background blur

Mark the subject and choose “Everything else” for a portrait-style blurred background.

Blur, pixelate or black box

Pick the look you want. For text that must stay secret, the black box can never be reversed.

How to blur part of an image

  1. 1

    Open your photo

    Drop a JPG, PNG, WebP or HEIC photo onto the box, or paste a screenshot with Ctrl+V.

  2. 2

    Mark what to hide

    Drag over each face, plate or piece of text. Use Oval for faces. Move or resize areas by dragging.

  3. 3

    Choose the effect

    Pick Blur, Pixelate or Black box and set the strength. Choose Everything else to blur the background instead.

  4. 4

    Download

Worth knowing

  • Image Blur Tool on Toolspire: blurs marked areas, everything except the marked areas (background blur), or the whole photo.
  • Three effects: smooth Gaussian blur, pixelate (mosaic) and a solid black box — with adjustable strength.
  • Mark areas as rectangles or ovals; drag to move them, drag a corner to resize, and press Delete to remove one.
  • The live preview matches the final image; the download is full resolution in the original format (JPG, PNG or WebP; HEIC becomes JPG).
  • Location and camera data (EXIF) are not copied to the blurred image.
  • Runs entirely in this tab — the photo is not sent to us.

Is blurred text really unreadable?

Not always. Light blur or small pixel blocks can leave enough of the shapes of letters and digits for software to guess them, especially for short numbers. For anything sensitive — Aadhaar, PAN, card or account numbers, passwords, OTPs — use Black box, or a strength of 60 or more so no detail remains.

For documents, a black box in Redact PDF removes the text itself rather than only covering it.

FAQ

Questions about Image Blur Tool

Where does Image Blur Tool run?

Image Blur Tool runs in this tab on Toolspire. What you type or drop in is not sent to us and is not stored on a server.

How do I blur a face in a photo?

Open the photo, choose Oval as the area shape and drag over the face. Set the effect to Blur with a strength of 50 or more, then download.

How do I blur the background of a photo?

Mark the person or object you want to keep sharp, then choose Everything else. Everything outside the marked areas is blurred.

Will the downloaded image be lower quality?

The size stays exactly the same. JPG and WebP photos are saved at high quality (92); PNG stays lossless.

Can someone un-blur my image?

A strong blur or pixelation can’t be undone to reveal faces, but weakly blurred text can sometimes be guessed. Use Black box for secret text and numbers.

Does it work on phones?

Yes. Drag with your finger to mark areas. To scroll past the photo, switch the toggle above it to Scroll page.

Is my photo uploaded?

No. The photo is processed in this tab on your own device and never leaves it.
