How to preserve track changes when converting Word document to PDF?

Syncfusion® .NET Word Library (DocIO) used to create, read, edit and convert Word documents programmatically without Microsoft Word or Interop dependencies. Using this library, you can preserve track changes when converting Word document to PDF in C#.

Steps to preserve track changes when converting Word document to PDF:

1. Create new C# .NET Core console application.

2. Install the Syncfusion.DocIORenderer.NET.Core NuGet package as a reference to your .NET Core application from NuGet.org.

3. Include the following namespace in the Program.cs file.

using Syncfusion.DocIO;
using Syncfusion.DocIO.DLS;
using Syncfusion.DocIORenderer;
using Syncfusion.Pdf;

4. Use the following code example to preserve track changes when converting Word document to PDF.

using (FileStream fileStream = new FileStream(Path.GetFullPath(@"Data/Template.docx"), FileMode.Open))
{
   //Loads an existing Word document.
   using (WordDocument wordDocument = new WordDocument(fileStream, Syncfusion.DocIO.FormatType.Automatic))
   {
       //Sets revision types to preserve track changes in  Word when converting to PDF.
       wordDocument.RevisionOptions.ShowMarkup = RevisionType.Deletions | RevisionType.Formatting | RevisionType.Insertions;
       //Creates an instance of DocIORenderer.
       using (DocIORenderer renderer = new DocIORenderer())
       {
           //Converts Word document into PDF document.
           using (PdfDocument pdfDocument = renderer.ConvertToPDF(wordDocument))
           {
               //Saves the PDF file to file system.    
               using (FileStream outputStream = new FileStream(Path.GetFullPath(@"Output/Output.pdf"), FileMode.Create, FileAccess.ReadWrite, FileShare.ReadWrite))
               {
                   pdfDocument.Save(outputStream);
               }
           }
       }
   }
}
