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. 1

    Upload your image into the editing workspace. The tool loads the picture and provides selection tools like a brush or rectangle. You can mark the specific areas you want to obscure.

  2. 2

    The engine applies a Gaussian blur algorithm to the selected regions. It averages the pixel colors in the area to create a smooth, unrecognizable effect. You can adjust the blur intensity using the provided slider.

  3. 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.
