How the Image Blurrer Works

This tool allows you to blur a specific area of an image or the entire image. When you upload, a blur area appears in the preview. Adjust it using the mouse or by entering numerical values. The area is defined by top, left, width, and height. Empty top/left default to zero; empty width/height default to the maximum size. Set the blur intensity in blur radius. Larger images may require larger radii. After previewing, click to apply the blur and download as JPG, PNG, or WebP.
