FAQ

Good to know.

How do I blur an image online?
To blur an image, open the Pixasur Blur Image tool, add your photo, and drag the blur slider until the softness looks right, then download it. The tool uses a gaussian blur applied in your browser, so you get a smooth result without installing any software.
Is the blur image tool free and private?
Yes, the Pixasur Blur Image tool is completely free with no sign-up and no watermark, and it runs entirely in your browser so your photo is never uploaded. Everything happens on your device, which keeps the original image private.
Can I control how strong the blur is?
Yes, the Blur Image tool uses an adjustable gaussian blur slider, so you can set anything from a slight softening to a heavy blur. A live preview shows the exact strength before you export the final image.
Can I blur just the background of a photo?
The Blur Image tool applies blur to the whole image with a strength slider, so it does not isolate a background on its own. To blur only faces, use the dedicated Pixasur Blur Face tool, or blur the full picture and place it behind other content for a uniform soft background.
What formats can I save the blurred image in?
The Blur Image tool exports the blurred result to JPEG, PNG, or WebP, and there is no file size limit on the photo you load. The re-encode runs on your device, so the download starts instantly with no upload wait.
