How to blur an image in three steps
- 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
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.

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. No account, no watermark, and no limit. Your file stays in the browser — you are not paying with an upload.
- Does my image get uploaded to a server?
- No. The editor opens your photo in this tab and paints on it here. Nothing is sent or stored. Closing the tab clears it. How to check that for yourself.
- Can I blur only one part of an image?
- Yes. That is the normal way. Drag a box over one region — a face, an email, a house number — and leave the rest sharp. Blur one part, keep the rest.
- Can I blur with a brush instead of a box?
- Yes. Pick Draw and trace the shape. It follows your finger or mouse — good for faces and odd shapes. Using the brush.
- Can I blur the background of a photo?
- There is no one-click AI background blur. Trace the background with Draw and blur it yourself. Slower, but the photo stays 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. Use Black bar for digits and secrets — it replaces the pixels, so there is nothing left to recover. What unblur tools really do.
- Which files can I open?
- PNG, JPG, WebP, and GIF. On a computer you can paste from the clipboard. Export iPhone HEIC as JPEG or PNG first.
- Does it work on a phone?
- Yes. Open it in Safari or Chrome, pick a photo, pinch to zoom on small text, and download the PNG to your camera roll.
