Image to DXF
for CNC and CAD.

DXF is about geometry, not appearance

DXF is a CAD exchange format. It stores lines, arcs and curves that machines and drawing software can follow. It is not designed to carry rich artwork, so think of a DXF as the outlines of your design rather than the painted picture. Vetorly rebuilds your PNG or JPG as shapes with smooth Bézier curves and few nodes, which gives CNC and laser programs clean paths instead of thousands of tiny segments.

Where DXF is used

• CNC routers and plasma or waterjet cutting, where toolpaths are made from outlines.
• Laser software such as LightBurn, which can import DXF as well as SVG.
• CAD programs such as AutoCAD for further drawing or dimensioning.

Prepare the image for cutting

1. Use a high-contrast design. Solid black shapes on white give clear boundaries.
2. Make sure bridges and thin connections are thick enough for your tool or material. A router bit or a plasma kerf has a real width.
3. Plan for islands. In letters like O and A, the inner shape needs a bridge or stencil approach if it must stay in place.
4. Remove decoration you do not intend to cut.

Units and scale: the usual surprise

DXF files do not always tell the receiving program which units they use. After import, measure the design and compare it to the size you want. Rescale if needed, then check again before running a job. Draw a known-size rectangle as a reference if it helps.

Checks after import

• Zoom into curves and make sure they are smooth rather than faceted.
• Look for duplicate or overlapping paths that would cut twice.
• Find open paths where your software expects closed shapes, which matters for pocketing and fill operations.
• Delete stray tiny shapes.
• Use separate layers or color groups to assign cut depths, if your software supports it.

Choosing the right tolerance

Before you cut, decide how closely the machine must follow the outline. A decorative wooden plaque forgives small deviations, while a part that must fit another part does not. If accuracy matters, cut a small test piece first and measure it against the design.
