Add Sticker Contour

Vector Sticker Contour

Traces the PNG alpha boundary into mathematical curves and strokes a real vector contour — no blur, no circular stamping. Everything runs right here in your browser.

2. Contour settings

Contour thickness

Contour color

Path simplification

Removes tiny raster stair-steps. Too high can erase intentional details.

Curve smoothing

Converts polygon corners into cubic Bézier curves without applying blur.

Minimum component area

Removes isolated alpha specks while preserving real sticker elements.

Fill small interior holes

Fills small fully-enclosed transparent spots inside the artwork with the contour color, instead of leaving them as gaps.

Alpha cutoff

Increase this when semi-transparent glow or shadows create unwanted outlines.

PNG render quality

Show traced vector pathAdd safe padding

Keeps the contour from being clipped at the canvas edge.

3. Export

Important: PNG output is still raster and will show pixels under extreme zoom. SVG keeps the contour as true vector curves at any scale; the embedded artwork itself remains raster.
