Common questions about converting PNG, JPG, JPEG, and BMP images into DXF outlines.
The public converter accepts PNG, JPG, JPEG, and BMP images. PNG is often best for line drawings and transparent artwork. JPG is fine for many scanned drawings, but compression artifacts can create extra contours if the image is low quality.
Raster tracing follows visible pixel transitions. Shadows, antialiasing, paper texture, compression noise, and colored fills can all become geometry. Clean the image first, increase contrast, remove the background, and crop around only the shape you need.
Treat the generated DXF as a starting point. Inspect it in CAD before using it for CNC, laser cutting, or fabrication. Scale the drawing, delete unwanted contours, and redraw tolerance-critical features manually.
Each uploaded image can be up to 5 MB. The browser may optimize large images before upload so the service stays responsive. The public service also limits anonymous conversions per browser client ID to reduce abuse and keep compute capacity available.
Uploaded images are processed to create the requested DXF and are intended to be temporary. Do not upload confidential, personal, customer-owned, export-controlled, or rights-sensitive material unless you are comfortable testing it in a public web service.
