Add a Black Outline to an Image

Black outlines are commonly used for stickers, logos, thumbnails, product graphics, and images placed on light backgrounds. A black outline adds contrast and definition around the subject without changing the image itself.

Add a White Outline to an Image

White outlines are the go-to choice for dark backgrounds, stickers, social graphics, thumbnails, and logos. A white stroke keeps your subject clearly visible on dark themes where a black outline would disappear.

Add an Outline to a PNG

Transparent PNG images work especially well because the tool uses the transparent area to detect the visible subject and create an outline around its shape. The background stays transparent in the downloaded PNG.

This makes the tool a simple PNG outline maker: upload a transparent logo or sticker, choose a color, and download a finished outline image online in seconds.

A typical sticker workflow: remove the background from your photo first, then add an outline around the subject, and download the final PNG. Remove the background first.

Outline vs Border: What's the Difference?

An outline follows the shape of the visible subject. A border usually follows the rectangular edge of the entire image. If you upload a transparent PNG of a person, an outline follows the person's shape, while a border would simply create a rectangle around the whole image.

This tool creates true outlines (also called strokes): the outline hugs your subject's contour, extends outward from it, and leaves the original image untouched underneath.
