What CAD formats does RunConvert support?

RunConvert converts DWG and DXF CAD drawings to and from formats like PDF, for free.

Can I share a CAD drawing with someone who doesn't have AutoCAD?

Yes - converting your DWG or DXF file to PDF lets anyone view the drawing without needing CAD software installed.

Does converting DWG or DXF preserve layers, scale, and dimensions?

Yes. Layer structure, drawing scale, and dimension annotations are preserved during conversion - only the file format changes, not the underlying drawing data.

Can RunConvert handle both older and newer DWG file versions?

Yes, RunConvert reads a wide range of DWG versions, from older AutoCAD releases through current formats, and converts them without needing the matching AutoCAD version installed.

Is there a file size limit for CAD conversion, and is it free?

Free conversions support CAD files up to 1GB, which covers the vast majority of architectural, mechanical, and engineering drawings, with no account or software installation required.
