Image Blur Tool
The Image Blur Tool is a free online application that softens or obscures parts of your pictures using a smooth blur effect. It is essential for privacy advocates, designers, and marketers who need to hide sensitive data or create background effects. You can use it anywhere to protect identities, blur license plates, or make text stand out on busy backgrounds.
How the Image Blur Tool works
- 1
Upload your image into the editing workspace and set the blur radius anywhere from 0 to 40px. The effect applies to the whole picture.
- 2
The engine applies a uniform Gaussian-style blur across the entire image, averaging neighboring pixels into a smooth, softened result that updates as you move the slider.
- 3
The blurred image is displayed with the sensitive areas successfully obscured. You can download the final picture in high quality. The image is now safe to share without compromising privacy or design balance.
