How to create a PDF/A Compliance document in C# and .NET

  1. Add SautinSoft.Document from Nuget.
  2. Load/Create a document.
  3. Specify PDF/A compliance in pdf save options.
  4. Save the document as PDF.

Let's create a simple PDF document from a DOCX file. By the way, this code shows - how to load an existing document and save it as a PDF/A compliant version.


                PdfSaveOptions options = new PdfSaveOptions()
            {
                // PdfComliance supports: PDF/A, PDF/1.5, etc.
                Compliance = PdfCompliance.PDF_A1a
            };
If you need to load an existing document (*.docx, *.rtf, *.pdf, *.html, *.txt, etc) and save it as a PDF/A compliant version, you need to point a path for this file: 

                // Path to a loadable document.
            string loadPath = @"..\..\example.pdf";
            //string loadPath = @"..\..\example.html";
            //string loadPath = @"..\..\example.rtf";

As the result, you will get the fully compatible PDF/A document
