As of version 8.2.0, PixEdit® Converter Server and PixEdit® Server are able to process PDF documents containing XFA forms.

XFA is used to integrate data filled by the user in PDF forms. Most PDF processors do not handle XFA content and will fail when it tries to open a document of this type.

To activate XFA support on PixEdit® Converter Server and PixEdit® Server, install the free virtual PDF printer PixJet® and Adobe Reader on the server. When these two applications are installed, simply restart the services by clicking “Server” and “Restart PixEdit Server…” in the upper right corner of PixEdit Server Manager.

PixJet® can be downloaded for free from this site.
