DXF is AutoCAD's text-based interchange format. Unlike the binary DWG, DXF is documented and parseable, which is why it's the default export when you need to move drawings between tools.

Why are some entities missing detail?

DXF supports hundreds of entity types. We render the common ones — LINE, ARC, CIRCLE, ELLIPSE, LWPOLYLINE, POLYLINE, SPLINE, POINT, SOLID, 3DFACE, TEXT, MTEXT — and skip esoteric or 3D-block entities. Dimensions render as their underlying geometry.

DWG is binary and proprietary; we recommend converting to DXF in your CAD package or with a free converter, then opening the DXF here.

No. Files are opened entirely in your browser using local JavaScript and WebAssembly. Nothing is sent to a server.

Does it work on mobile?

Yes. The viewer is mobile-first and works on phones, tablets, and desktops.

About DXF

AutoCAD Drawing Exchange Format.

DXF (Drawing Exchange Format) is the human-readable CAD interchange — AutoCAD's open companion to DWG, used everywhere from architectural plans to laser-cutter toolpaths. We parse the file with dxf-parser, then render lines, arcs, polylines, ellipses, splines, and text directly to SVG with layer toggles, pan, and zoom.
