Add an Outline to a PNG – Online PNG Maker

This browser-based utility adds an outline to PNG images. It allows you to highlight elements in PNG images, giving them contrast and clarity with a customizable outline. You can choose the desired width, color, and intensity of the outline in the options, integrating it into the PNG context. The width of the outline is specified in pixels. For smaller-sized PNGs, a 1-10 pixel outline is often sufficient, while larger PNGs may benefit from a thicker 10-30 pixel outline. The outline color can be selected from the palette, or specified by name or code in the option. You can also choose the position of your outline, namely, whether to place the outline around all edge pixels, or only those edge pixels that extend to the outside of the PNG objects. To create a more natural-looking outline, you can smooth its edges. To create a semi-transparent outline, you can enable the halo effect mode, which turns the outline pixels into semi-transparent glowing pixels. Png-abulous!
