The Full Form of DWF is‍ Design Web Format.

Design Web Format (DWF) is an open and secure file format created by Autodesk and mainly used for representing rich design data. The file format is independent of the application hardware, software or operating system, and can capture all the design intent information that needs to be represented. Design Web Format is highly capable of including intelligent metadata relevant to design intent. Design Web Format can help project teams in standardizing on a common file format for transmitting design and drawing sets.

Design Web Format is not a replacement for other file formats such as CAD, but it helps creators, designers, publishers and engineers in viewing, printing and publishing rich design data. The file format was specifically made for representing design data, delivering multi-sheets, and with Web-ready capabilities along with printing and viewing capabilities. There are many viewers published by Autodesk for viewing and publishing the Design Web Format files. Alternatively, other third-party applications are also available for viewing Design Web Format files. One salient aspect of the Design Web Format is its ability to publish multiple layouts simultaneously.
