Applications without powerful PDF support are unthinkable today, so many companies already relay on our powerful PDF creation engines wPDF and wPDFControl. With WPViewPDF we provide a powerful component to view and print, and the with the “PLUS” edition also modify PDF files.

With our WPViewPDF you can license a powerful tool (for .NET and as VCL for Delphi in one package!) to display and manipulate PDFs right in your application! Since the main PDF engine was compiled into a DLL (32 bit and 64bit are provided) it is also possible to call some DLL functions directly, such as pdfPrint and pdfMerge. This also works from C++ and VB6. To support old VB6 application even further we also included an ActiveX interface into the WPViewPDF package.
