You can do that using specialized PDF toolkit. Using LEADTOOLS PDF features you can copy the original file then combine the new copy to the original file. You can do it using 2 lines of code like this: Leadtools.Pdf.PDFFile firstPdf = new Leadtools.Pdf.PDFFile( "Original.pdf" ); firstPdf.MergeWith( new string [] { "Copy.pdf" }, "Final.pdf" ); Also, you can repeat these lines several times to get 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" ); } Also, you can use Virtual Document Library to construct documents consisting of pages from different input documents.
