About the Add Rounded Square black outline icon
A thick plus sign sits centered inside a rounded-corner square frame, forming a self-contained button shape. It works as a universal add or create action, fitting toolbars, floating action buttons, form controls, list-item add buttons, and mobile app interfaces.
The square's rounded corners soften the button silhouette while the plus strokes match the frame's line weight for visual balance. Pairs naturally with remove, edit, or settings buttons in a UI icon set; keep proportions intact when resizing so the frame doesn't look cramped.
This is the black outline version of the add rounded square icon: even, monoline strokes that stay crisp at small sizes and suit clean, minimal interfaces, wireframes and light backgrounds.
