How much blur to use, and where
Smooth Gaussian blur
A real Gaussian blur produces soft, natural falloff with no blocky artefacts. A single slider takes you from a gentle haze to a heavy frost, and the softening spreads evenly across the whole image so the result looks intentional rather than accidental or out of focus.
How the blur works
The tool applies the browser canvas Gaussian blur filter directly to your uploaded image. Each pixel is blended with its neighbours using a bell-curve weighting, which is why the transition stays smooth. Everything runs on an HTML canvas, so the preview reacts the moment you move the slider.
Obscure the sensitive bits
Blur out faces, plates, or private details before sharing a screenshot. A light blur softens without destroying context, but be aware it can sometimes be partly reversed. For a hard, unrecoverable block on sensitive content, the Pixelate tool is the stronger choice.
Blur versus pixelate
Blur keeps shapes readable and adds a dreamy, cinematic mood, which suits backgrounds and frosted overlays. Pixelate breaks the image into hard square blocks and fully removes detail, which suits censoring. Pick blur for aesthetics and softness, pixelate when the goal is to hide something completely.
Tips for the best result
Start with a modest amount and raise it gradually rather than jumping to maximum. On a transparent cutout, keep the blur gentle so the alpha edge stays crisp. For frosted overlays that sit behind text, a stronger blur gives you a cleaner, more even surface to type over.
How to blur an image
Upload your image
Drop in a PNG, JPG, WebP, or SVG. The image loads onto the canvas and appears in the preview panel right away.
Set the blur amount
Drag the slider from a light softening to a heavy blur. The result updates live against the original so you can find the exact strength you want.
Preview and download
Check the softened image in the preview. Downloading the full-resolution version uses one credit and a free account.

When blurring is the point
Soft backgrounds
Blur a busy backdrop so your subject or headline text stands out clearly.
Privacy
Hide faces, names, or numbers before posting a screenshot publicly.
Frosted overlays
Create a soft image layer to place UI cards or headings over.
Depth and mood
Add a dreamy, out-of-focus feel to a photo or hero image.
Thumbnails
Soften a background image so an overlaid title reads at small sizes.
Or just ask

Type what you want changed and the assistant does it on the canvas — useful when the edit is easier to say than to find.
