An example from this https://pdfium.patagames.com/c-pdf-library/ called How to Merge PDF Files in C# This examples shows how to merge two separate files. Its load first file and second file. But if you replace second to first, than it would be exactly what you want. /// /// Merge PDFs in C# using PDF Library /// public void MergePdf() { //Initialize the SDK library //You have to call this function before you can call any PDF processing functions. PdfCommon.Initialize(); //Open and load a PDF document in which will be merged other files using (var mainDoc = PdfDocument.Load(@ "c:\doc1.pdf" )) // C# Read source PDF File #1 { //Open another PDF document. In our case that should be doc1.pdf again. using (var doc = PdfDocument.Load(@ "c:\doc1.pdf" )) //Read PDF File #2 { //Import all pages from document mainDoc.Pages.ImportPages( doc, string .Format( "1-{0}" , doc.Pages.Count), mainDoc.Pages.Count ); } mainDoc.Save(@ "c:\ResultDocument.pdf" , SaveFlags.NoIncremental); } }

You can do that using specialized toolkit. Using LEADTOOLS you can copy the original file then combine the new copy to the original file. The code is very simple like this: Leadtools.Pdf.PDFFile firstPdf = new Leadtools.Pdf.PDFFile( "Original.pdf" ); firstPdf.MergeWith( new string [] { "Copy.pdf" }, "Final.pdf" ); You can repeat these lines several times to duplicate more pages like this: for ( int i = 0; i { PDFFile original = new Leadtools.Pdf.PDFFile(@ "Original.pdf" ); original.MergeWith( new string [] { @ "Copy.pdf" }, @ "Copy.pdf" ); } For more details see this link: https://www.leadtools.com/sdk/pdf
