StickerBleed

StickerBleed adds a contour border that follows the shape of a transparent PNG instead of drawing a square frame around the canvas. Upload a transparent PNG (up to 4000×4000px, 10MB), choose a thickness from 2 to 20px and a color (white is the default), preview the original against the result, and download a print-ready PNG. It is built for sticker makers and Etsy/POD sellers who need white outlines, sticker bleed, or die-cut margins, and it also works as a general image outline generator. Free with no signup: 10 generations per IP per day.
