The Blur tool is specifically designed to soften the edges of an image, creating a smoother and more blended appearance. When you apply the Blur tool to a selected area or along edges, it effectively reduces the sharpness and intensity of the colors, producing a transition that feels more organic. This technique is particularly useful for blending harsh lines, making it an essential tool in graphic design and photo editing when the goal is to create a seamless look.

In contrast, while the Smudge tool can also help create a blended effect, it works by dragging pixels from one area to another, which might not result in the softening effect that the Blur tool provides. The Brush tool is primarily used for painting or drawing and does not inherently blend edges; it lays down color or texture without the same smoothing effect. The Gradient tool, meanwhile, is designed for creating gradual transitions between colors, but it does not specifically target blending edges of an existing image or selection. Each of these tools has its own purpose, but the Blur tool stands out as the most effective for achieving a smoother appearance.
