Sticker Outline Maker
Drop a design and get it back with a smooth die-cut border, white or any color, sized in real inches at 300 DPI. Gaps inside the outline are filled so a cutter follows one clean edge. It runs in your browser: nothing is uploaded.
A border in real units
Pick the width in pixels or tap 1/32, 1/16, 1/8 or 3/16 inch at 300 DPI, and see the final sticker size in inches before you download.
One clean cut line
Gaps between letters and inside shapes are filled by default, so the outline is a single smooth contour a cutter can follow.

Why a sticker design needs a border
A die-cut sticker is cut along a line that follows the shape of the design. Cutters are precise but not perfect, so a cut that runs right at the edge of the artwork can nick a letter or leave a sliver of the backing. A solid border around the design gives the blade room to land, makes thin parts sturdier, and is the look most buyers expect from a die-cut sticker.
Getting a clean sticker file
- Start from a transparent PNG. The border follows the pixels that are not transparent. A design saved on white has its outer white removed first, but a real transparent export gives the cleanest edge.
- Work at print size. At 300 DPI, a 3-inch sticker is 900 pixels wide. The size line under the preview shows what your file prints at; the DPI checker tells you whether the design is sharp enough for it.
- Keep the outline simple. A wider border smooths spiky shapes into an easier cut. Leave the gap filling on unless you want the cutter to go inside the design.
- Check the template of whoever prints it. Print shops and marketplaces publish their own sticker sizes and bleed. Size the finished file to match with the image resizer.
If your design sits on a white or solid background, the background remover gives you more control over that step before you add the border here.

Frequently asked questions
How do I add a white border to a sticker design?
Drop the design above, ideally a transparent PNG. The tool grows the shape of the design outward by the border width you pick, fills it with white (or any color), and puts the design back on top. Download the PNG and it is ready to size for your printer.
How wide should a sticker border be?
It depends on who cuts it, so check their template first. As a starting point, the buttons give 1/32, 1/16, 1/8 and 3/16 inch at 300 DPI; wider borders are easier to cut and smooth out spiky shapes, narrower ones keep the sticker closer to the artwork.
Do I need a transparent background?
It works best with one, because the border follows the pixels that are not transparent. If the image has no transparency, the tool removes the background that touches the edges first. For a design on a busy background, cut it out before adding the border.
Will the cut go between the letters?
Not by default. The gaps inside the outline are filled with the border color, so the sticker has one outer edge. Untick the option if you want those gaps left transparent.
Is my design uploaded?
No. The image is read and processed in your browser and the PNG is made on your device. Nothing is sent to a server, and there is no daily limit.
