DXF and DWG are the two most popular CAD formats worldwide. DXF is an open exchange format, while DWG is AutoCAD's proprietary format. The choice depends on your workflow.
In-depth guide: DXF or DWG for your drawing →
| Criteria | DXF | DWG |
|---|---|---|
| Open standard | ✓ | ✗ |
| File size | Large (text) | Compact (binary) |
| CAD compatibility | All CAD software | AutoCAD + compatible |
| Text editing | ✓ | ✗ |
| Layers & blocks | ✓ | ✓ |
When you need maximum compatibility across different CAD platforms, data exchange with partners, or work in NanoCAD/FreeCAD.
When you work in AutoCAD and file compactness matters, plus preserving all proprietary properties.
