The system, step by step
In this case study, we cover an offline conversion library for DWF and DWFX design files. The client needed PDFs produced on their own machines, without sending drawings to an outside service.

What the brief demanded
Offline conversion of two related file formats brought a few clear requirements:
The client
The client was based in Israel and worked with design drawings in DWF and DWFX formats. Their files had to stay local, which ruled out the usual cloud conversion tools.
- Running entirely offline, with no calls to an external service.
- Handling both the DWF and DWFX formats in one library.
- Packaging the work as a library the client could drop into their own tools.
Built and handed over
We built a Python library that reads DWF and DWFX files locally and writes PDFs, delivered as a package the client could install and call from their own code.
- A Python library for local DWF and DWFX to PDF conversion.
- A first version for review, then a revised version after the client's feedback.
The first version was delivered in early November 2025 and a revised version followed within a week. The project closed in late November 2025 with the client's five-star rating.
