Vectorize a logo for laser cutting or CNC

A cutting machine needs closed outlines, with no duplicates and few vertices, at real size. LineWorkCAD vectorizes your logo, checks for those problems and exports it as DXF or SVG. Everything runs in your browser: your file is never uploaded to a server.

What a cutting machine needs

• Closed outlines: a tiny gap between two ends can make the laser fail to cut a piece or make the tool stop.
• No duplicate lines or crossings: if a line is there twice, the machine cuts it twice.
• Few vertices: thousands of points on a curve slow the machine down and leave a rough cut.
• Real size: the file must measure what the part measures.

How to prepare a logo, step by step

1. Open the logo (PNG, JPG…). For cutting, switch the mode to Black and white (silhouettes) and adjust the threshold until the shapes are well defined. With “Invert” you choose whether the cut part is the dark or the light one.
2. Set the final width in millimeters so the drawing comes out at real size.
3. Clean up: “Remove specks” deletes stray dots; “Simplify” and “Reduce vertices” leave few points; “Smooth” removes the teeth of pixelation while keeping real corners.
4. Fix: “Fix” closes gaps, trims overshoots and checks crossings. The error circles mark what it could not fix on its own.
5. Convert what is almost exact: “Recognize shapes” turns almost perfect curves into exact circles and arcs; “Straighten” aligns almost horizontal or vertical segments.
6. Measure and export. Check the dimensions with the dimension tools and save the DXF.

Tips

• Letters with holes (O, A, B…) keep their hole as an inner outline.
• Start from the highest-resolution image you have: a blurry logo gives uneven edges.
• Always check the file in your machine’s software before cutting material.
