This browser-based tool adds an outline to a PNG icon, helping it stand out on any background and become more noticeable and readable. The outline can be thin and barely visible or thick and expressive. Its thickness can be set in pixels in the options. The outline can be applied either to all edges touching transparent areas or solely to the outermost borders of the icon, excluding internal shapes. The outline color can be specified by name, hex, or RGB code or chosen from the attached palette. Additionally, you can make the pixels on the edges of the outline semi-transparent, creating a smoothing and fading effect. You can also turn the solid stroke into a radiance effect, transforming it into a glowing light emanating from the icon. Png-abulous!

In this example, we apply a thin black outline, 3 pixels wide, to a light slate gray mail envelope icon. This stroke emphasizes the edges of the icon and ensures it is well-visible on both light and dark backgrounds. (Source: Wikipedia.)
In this example, we add a decorative khaki-colored outline to a bagel icon. We specify the stroke thickness as 22 pixels and apply it to the outer side of the icon, leaving the hole of the bagel without an outline. (Source: Wikipedia.)
In this example, we add a thick stroke to a poison mushroom icon and transform it into a glow effect. The outline is 30 pixels wide, and the glow effect creates a luminous halo of dark purple color (#47086d). (Source: Wikipedia.)
