How To Blur Background In Adobe Illustrator

If you are an illustrator, graphic designer, or just someone who loves using Adobe Illustrator, you may have questioned how to blur the background of your designs. This technique can enhance your designs, providing them with a more polished and sophisticated appearance. This blog post will walk you through the necessary steps to achieve this result.

Step 1: Create Your Background

First, you need to create the background for your design. You can do this by selecting the Rectangle Tool from the toolbar. Then, click and drag across your artboard to create a rectangle. We will apply the blur effect to this rectangle.

Step 2: Apply the Blur Effect

Once the background is ready, you can add the blur effect. To do this, click on your rectangle to select it. Then, go to Effect > Blur > Gaussian Blur.

In the Gaussian Blur dialog box, set the radius to control the amount of blur. The higher the radius, the stronger the blur effect will be. Click OK when you are happy with the settings.

Step 3: Adjusting the Blur Effect

If you want to adjust the blur effect later, you can do that easily. In the Appearance panel (Window > Appearance), you can find the Gaussian Blur effect applied to your rectangle. Click on Gaussian Blur to open the dialog box again, where you can adjust the radius.
