Hello Sunny, You can merge pdf files into a single pdf easily with Spire.PDF. Here is a simple example for you: using System; using Spire.Pdf; namespace MergePDFs { class Program { static void Main(string[] args) { //Get the paths of the documents to be merged String[] files = new String[] { "C:\Users\Administrator\Desktop\PDFs\sample-1.pdf", "C:\Users\Administrator\Desktop\PDFs\sample-2.pdf", "C:\Users\Administrator\Desktop\PDFs\sample-3.pdf"}; //Merge these documents and return an object of PdfDocumentBase PdfDocumentBase doc = PdfDocument.MergeFiles(files); //Save the result to a PDF file doc.Save("output.pdf", FileFormat.PDF); } } } You can visit this link for more detailed information: https://www.e-iceblue.com/Tutorials/Spire.PDF/Spire.PDF-Program-Guide/Merge-PDF-Files-with-New-Method-in-C.html#1

You can use the PDFFile MergeWith method to combine multiple PDF files in one PDF file. Here is some code which demonstrates this: string sourceFileName1 = @"C:/Input/File1.pdf"); string sourceFileName2 = @"C:/Input/File2.pdf"); string sourceFileName3 = @"C:/Input/File3.pdf"); string destinationFileName = @"C:/Output/Merged.pdf"); // Merge 1 with (2, 3) and form destination PDFFile pdfFile = new PDFFile(sourceFileName1); pdfFile.MergeWith(new string[] { sourceFileName2, sourceFileName2 }, destinationFileName); https://www.leadtools.com/help/sdk/dh/pdf/pdffile-mergewith(string[],string).html https://www.leadtools.com/help/sdk/tutorials/dotnet-winforms-merge-pdf-files-to-single-pdf-file.html
