Image Blur

The Image Blur tool applies a Gaussian blur effect to your images with precise control over the blur radius. Upload any image, adjust the intensity slider, and see the blurred result update in real time. This is useful for creating background images, obscuring sensitive information, adding depth-of-field effects, or softening textures for design purposes.

Gaussian blur is one of the most common image processing operations in photography and design. It smooths out detail by averaging each pixel with its neighbors, weighted by a bell-curve distribution. A small radius produces a subtle softening effect, while a large radius creates a dreamy, heavily blurred look. This tool implements the StackBlur algorithm, which is optimized for fast performance in the browser even on large images.

The real-time preview lets you dial in exactly the amount of blur you want before committing to a download. Use it to blur entire images or combine it with other tools for creative workflows - for example, create a blurred background version of an image for use behind text overlays. All processing runs client-side via Canvas, so your images remain private.
