DWF to PDF Converter for .NET and Free Online Use

DWF stands for Design Web Format. Architects and engineers publish drawings in it because the file is far smaller than the CAD original and contains only what a reviewer should see, without the editable geometry behind it.

The remaining problem is the viewer. A client, a contractor or a planning office may have no design software at all, and a DWF attachment cannot be opened. PDF is opened by every operating system, every phone and every browser, and it prints at the correct scale.

GroupDocs.Conversion Cloud reads the DWF file and writes a PDF, keeping line work and sheet layout as published. A drawing set with several sheets can be converted completely or by page range, the output quality is a request setting, and a watermark or a password can be applied to the PDF.

A .NET service calls this through the SDK with a Client ID and Secret, which suits a document pipeline that receives drawings from several projects. For a single file the free online converter is enough, and the API Explorer shows the parameters in advance.
