Yes — DXF (Drawing Exchange Format) is AutoCAD's open interchange format and is supported by virtually every CAD application: AutoCAD, FreeCAD, LibreCAD, DraftSight, SolidWorks, Fusion 360, and more. It was designed specifically for cross-application compatibility.
Converting a raster image (PNG/JPEG) to DXF requires a vectorisation step that traces the image edges into paths. Results depend heavily on the source image: high-contrast black-and-white images with clean edges give the best results. Blurry edges, gradients, or complex photos produce messy, over-detailed paths that laser cutters struggle with. For clean laser-cut DXF files, start with a clean black-and-white silhouette at high resolution.
This usually happens when the DXF drawing is on a white or very light layer against a white background, or when the drawing coordinates are very far from the origin (0,0) — a common issue in CAD files. Try opening the DXF in a CAD viewer and checking the layer visibility and zoom-to-fit before converting.
For on-screen documentation: 150 DPI is sufficient. For printed documentation: use 300 DPI. For large-format prints or technical drawings where fine detail matters: 600 DPI. Since DXF is vector-based, you can export at any resolution without quality loss — always export at a higher resolution than you think you need.
