PDF Viewer XFA PDF Form

Hi, what options we have to allow web app users to import or export data into/from an xfa form?
Just show upload pdf and upload xml into pdf/extract xml from pdf buttons? (as I assume that xfa forms cannot be loaded into PDF Viewer, is this correct?)

Or is it better to build the app as a desktop application? In this environment are they going to be able to view the xfa form in PDF Viewer and use the import/export XML into/from XFA form?

Thank you

Hi Asad,
I have Aspose.PDF for .Net: https://reference.aspose.com/pdf/net/
Thank you


The Aspose.PDF for .NET does not provide any PDF Viewer to integrate with your web applications. You can however implement the API in the code-behind to convert PDF into images and display those images in the HTML canvas or Image Control in web/desktop applications. Similarly, you can fill the XFA Form in PDF by importing XML using Aspose.PDF in the back end and generate images from filled PDF to display them in the front end. Please feel free to let us know in case you need more information.

Interesting idea, might work.
Thank you
