How to blur an image in three steps

  1. 1

    Open your image

    Pick a photo or screenshot from your phone or computer, or paste one on desktop. The file stays in this browser tab — it is never uploaded.

  2. 2

    Blur the part you want hidden

    Blur is already selected. Drag a box over a face or a name, or switch to Draw to brush around an odd shape. Use Black bar for emails, phone numbers, and card digits.

  3. 3

    Download the PNG

    Save redacted.png and share that copy instead of the original. Clear image, or just closing the tab, drops your photo from memory.

Questions people ask

Is this blur image tool free?
Yes. There is no account, no watermark, and no limit on how many images you blur. You are not paying with an upload either — the file stays in your browser.
Does my image get uploaded to a server?
No. The editor opens your photo in this tab and paints on it there. Nothing is sent anywhere, nothing is stored, and closing the tab drops the file from memory. How to check that for yourself.
Can I blur only one part of an image?
That is the normal way to use it. Drag a box over the one region you want hidden — a face, an email address, a house number — and the rest of the photo stays sharp. Blur one part, keep the rest.
Can I blur with a brush instead of a box?
Pick Draw and trace around the shape you want covered. It follows your finger or mouse, so it suits faces, logos, and anything that is not a neat rectangle. Using the brush.
Can I blur the background of a photo?
There is no one-click AI background blur here. You trace the background with Draw and blur it yourself, which is slower but keeps the photo on your device. Blurring a background by hand.
Can someone unblur the image afterwards?
A light blur over short text can sometimes be read back. That is why the Black bar tool exists: it replaces the pixels instead of smearing them, so there is nothing left to recover. What unblur tools really do.
Which files can I open?
PNG, JPG, WebP, and GIF all work, and you can paste straight from the clipboard on a computer. iPhone HEIC photos need to be exported as JPEG or PNG first.
Does it work on a phone?
Yes. Open it in Safari or Chrome on iPhone or Android, pick a photo, pinch to zoom in on small text, and download the finished PNG to your camera roll.
