Upload a PNG or JPG and get back a laser-ready SVG with paths running along the center of each stroke.
Normal fonts and artwork engrave as filled outlines, which the laser traces around both edges. Centerline trace reduces a stroke or thin shape to one path down the middle, so the laser follows a single crisp line. Ideal for line text, signatures, and fine detail.
For single-line engraving of text and thin artwork, so the laser traces one line instead of outlining both edges.
