Tool Options

Stroke Width and Color

Thickness of the stroke.
Color of the stroke.

Outer and Smooth Stroke

Add stroke only to the outer edges of objects.
Enable outline anti-aliasing.

Glow Effect

Convert a stroke into a semi- transparent halo that's more intense near the object and diffuses in all directions.

What Is a PNG Stroke Adder?

This browser-based utility adds a stroke to all PNG objects. You can wrap objects in a thin or thick bezel, add extra pixels around logos, and make digital signatures bolder. The program works only with PNGs that have a transparent background. It finds all the pixels in contact with a transparent background and adds a line along the contact points. You can specify the stroke width (in pixels) and color (using the color's name, hex, RGB, or RGBA code) in the options. If you want the outline to be added only to the outer pixels of the objects, you can activate the "Add Only Outer Stroke" option. Also, you can use the "Smooth Stroke" option to enable anti-aliasing and make the pixels around sharp edges semi-transparent and smooth. The program also has a glow effect option that converts a solid stroke that surrounds the object into a semi-transparent stroke that smoothly diffuses in all directions, creating a soft, luminous halo. To make the glow mode look nice, it's recommended to use a larger stroke thickness, for example, 20 pixels or more. To remove existing strokes from PNG images, you can use the Remove Stroke from PNG tool. Png-abulous!

Add Stroke to a Seagull

In this example, we add a stroke to a flying seagull on a transparent PNG. We set the border color to steel blue and make it 4px thick. We also activate the stroke smoothing option so that the pixels around the seagull are anti-aliased and without rough edges. (Source: Pexels.)

Outline a Donut

This example wraps a pink donut in a translucent stroke. Since it uses the "Add Only Outer Stroke" option, the outline is only added around the donut, and the hole inside the donut remains unchanged. The outline is set to be 9 pixels wide and its color is 40% translucent pink. (Source: Pexels.)

Make a Signature Thicker

In this example, we make Henry Ford's signature a little bit thicker. We load a photo of Ford's signature that's written in black ink on a transparent background into the input and add a 2-pixel black line to the outer edges. The result is a bold signature that is better visible when added to digital documents. (Source: Wikipedia.)
