A rectangular border only frames the canvas. A contour outline wraps letters, mascots, and die-cut sticker shapes so the edge matches what a cutter will follow.
If you came here from an “add border to image” search, this page is the same core engine focused on outline wording and use cases.
Transparent PNG works best. Images without transparency may produce poor outlines.
