Open the CAD ViewerWhat Is the Difference Between DXF and DWG?
DXF (Drawing Exchange Format) is an open, text-based CAD file format created by Autodesk for interoperability between different CAD programs. DWG is AutoCAD’s native binary format — more compact and feature-rich.
Both formats contain similar data (geometry, layers, dimensions, text), but DWG files are smaller and faster to parse. Most CAD software can save in either format.
Our free DWG viewer currently reads DWG R2000 (AC1015) files natively. Native DXF support is on our roadmap. In the meantime, you can convert DXF to DWG using free tools like FreeCAD or LibreCAD.
