Merge PDF Documents
Hi there,

Does anyone know a way to merge 2 or more PDF documents into a single PDF file using ASP.NET?? This may potentially be used on a number of systems, so I would prefer it if I could achieve this in the ASP.NET code itself (so I don't have to install software or components on each machine the let me do it...)

PDF Merge and Split libraries from http://www.winnovative-software.com or http://www.dotnet-reporting.com are very reliable. The PDF merge tool allows you to merge PDF, HTML, texts and images.

You can build your own PDF merge utility using the PDF Merge and split libraries for .NET from from http://www.dotnet-reporting.com or http://www.winnovative-software.com .
You can use it to merge PDF files, html files, text files and images,
set the page orientation, compression level and page size.

All this can be accomplished with only a few lines of code:


PdfDocumentOptions pdfDocumentOptions = new PdfDocumentOptions();
pdfDocumentOptions.PdfCompressionLevel = PDFCompressionLevel.Normal;
pdfDocumentOptions.PdfPageSize = PdfPageSize.A4; pdfDocumentOptions.PdfPageOrientation = PDFPageOrientation.Portrait;
PDFMerge pdfMerge = new PDFMerge(pdfDocumentOptions);

You can find the full code sample on the PDF Merge Code Sample page

Please directly use the following code to achieve PDF merging :

using RasterEdge.Imaging.Basic;
using RasterEdge.Imaging.Basic.Core;
using RasterEdge.Imaging.Basic.Codec;
using RasterEdge.Imaging.PDF;

namespace RE__Test
public partial class Form1 : Form
public Form1()

public static string FolderName = "c:/";

private void button1_Click(object sender, EventArgs e)
string fileName1 = FolderName + "Sample1.pdf";
string fileName2 = FolderName + "Sample2.pdf";
string fileNameMerged = FolderName + "Merged.pdf";

REDocument doc1 = REFile.OpenDocumentFile(fileName1, new PDFDecoder());//use PDFDecoder open one pdf file

REDocument doc2 = REFile.OpenDocumentFile(fileName2, new PDFDecoder());//use PDFDecoder open another pdf file

BaseDocument docMerged = doc1.MergeDocument(doc2);//merge two pdf

REFile.SaveDocumentFile((REDocument)docMerged, fileNameMerged, new PDFEncoder());//save new pdf
