What is a .OFD file?
Everything worth knowing about Open Fixed-layout Document files.
An OFD file is an Open Fixed-layout Document, China's national standard (GB/T 33190) for fixed-layout documents, functionally similar to PDF. To open it, use Founder OFD Reader or Foxit PDF Reader with the OFD plugin on Windows, or WPS Office on any platform. Adobe Acrobat does not support OFD.

Is my .OFD file uploaded anywhere?
No. Your .OFD file is read and converted for you. The first time, a small open-source conversion component is downloaded and then cached.
Why does my older .OFD file look plain?
Some older word-processor files keep their formatting in a complex binary layout. The viewer shows all the text and tables reliably; richer formatting for those files is coming with server-side conversion.
Are macros in a .OFD file safe here?
Yes. The viewer never runs macros. It only reads the document text, styles and images, and tells you when a file contains macros.
Can I edit my .OFD file?
This is a viewer. You can copy the text or save it as HTML/TXT and edit it elsewhere. An online editor is on our roadmap.
It says my .OFD file is something else. Why?
We check the file's signature, not just its name. If a file was renamed, the viewer tells you what it really is and which tool opens it.
