What does Image Blur Tool do?
Apply a Gaussian blur across an entire image, or draw rectangles over faces, number plates, addresses and account numbers to redact them. The blur is baked into the exported pixels, so it cannot be reversed.
How to Use Image Blur Tool
- 1Load your imageScreenshots and photos both work.
- 2Choose a modeBlur everything, or draw regions to blur selectively.
- 3Set the strengthIncrease the radius until the detail is unreadable.

Key Features
- Whole-image Gaussian blur with an adjustable radius
- Draw one or more rectangles to blur only those areas
- Solid-fill redaction mode when blur is not strong enough
- The effect is applied to the exported pixels, so it cannot be undone
- Live preview at full resolution before download
Frequently Asked Questions
Can a blurred image be un-blurred?
Not from the exported file. The blur is applied to the pixel data itself and the original information is destroyed. This is different from a blur applied as a layer in a document, which can be removed.
Is blur strong enough to hide text?
Only at a high radius. Light blur on short text — a six-digit code, a number plate — can sometimes be recovered by specialised techniques. For anything genuinely sensitive, use the solid-fill redaction mode instead.
How do I blur just a face?
Switch to region mode and drag a rectangle over the face. You can add several rectangles for group photos. Everything outside the rectangles stays sharp.
Does this remove metadata as well?
Yes, as a side effect. The image is redrawn on a canvas and re-encoded, so EXIF including any GPS coordinates is not carried into the exported file.
Blurring happens entirely on your device. Since sensitive screenshots are exactly what this tool is for, nothing is uploaded at any point — you can go offline before loading the image.
