Integrate PDF functionality into your software

Integrate PDF functionality into your software

With the PDF Xpansion SDK you offer PDF functionality in your software – e.g. a viewer, a full-featured PDF editor or powerful annotation tools in PDF documents. The SDK supports almost all languages worldwide.


You want to integrate eInvoice functions into your software and create ZUGFeRD, XRechnung and/or Factur-X invoices (for all formats: Syntax UN/CEFACT Cross Industry Invoice) in the latest version and according to the current standard as well as EU Norm EN 16931? This is easily possible with the PDF SDK.
Zugferd, Xrechnung, Factur-X
XPS- and OXPS features

More core functions

Conversion from/to multiple format(s) is quickly implemented: XPS/OXPS, TXT, raster images, SVG, EMF & HTML. Integration of further XPS/OXPS functionality is also possible.

Viewing and processing dynamic forms (XFA format) for C++ and .NET applications can also become part of your software: Preview in the viewer (without filling in the forms), printing, using the API to access form data (read & fill). The SDK supports Universal Windows Platform (UWP) in addition to the latest Windows operating systems.

PDF/A fucntionality

With the developer library you can include in your applications functions for creating PDF/A-1-, PDF/A-2-, PDF/A-3 and PDF/A-4-files. All currently existing conformance levels (a, b, u) of the PDF/A format are supported. In contrast to PDF/A-1, the PDF/A-2 standard allows, among other things, compression with JPG2000, transparent elements and PDF layers. PDF/A-2 files may also embed PDF/A documents. In files that comply with the PDF/A-3 standard, not only PDF/A files but any files may be embedded. Thus, for example, the source file can be embedded in a PDF/A-3 file as part of an archive solution or an XML file for invoice processing systems using ZUGFeRD solution.
