DWG → DXF Converter

Free · runs in your browser

Convert AutoCAD DWG drawings (R13 to AutoCAD 2018) to DXF without uploading them anywhere. The conversion runs inside your browser, so your drawing never leaves your device.

Drag and drop a .dwg file here or

No file selected

Supports DWG from AutoCAD R13 to AutoCAD 2018 (and most older releases). Output is ASCII DXF in the same version as the drawing, or the version you choose. DXF → DWG and DGN are not supported. Objects created by third-party applications may be skipped; the converter tells you when that happens. Verify the result in your CAD software before relying on it. Engine: GNU LibreDWG 0.14 compiled to WebAssembly (GPL-3.0-or-later).
