This tool allows you to blur a specific area of an image or the entire image. When you upload an image, the blur area will immediately appear in the preview window. You can adjust this area by using the mouse or entering numerical size values in the options. The blurred area is defined by four parameters: top position (distance from the top), left position (distance from the left side), width (width of the area in pixels), and height (height of the area in pixels). If you leave the top or left parameters empty, they will be set to zero. Similarly, if you leave the width or height parameters empty, they will be set to the maximum value. Once the area is selected, everything within it will acquire the blur effect. You can specify the strength of the blur effect in the blur-radius option. Depending on the size of your image, you may need to enter a different blur radius. For example, a 10-pixel radius may be suitable for a 600×400-pixel image, while an 80-pixel radius may be needed for a 2000×1400-pixel image. You can see a live preview of the blur effect in the output window. Additionally, you can download the blurred image by selecting the desired file extension in the options. The supported file extensions are JPG, PNG, and WebP. Image-abulous!
