You can merge PDF files of different sizes using LEADTOOLS PDFFile class. This class has a MergeWith() method that you can use as follows: string sourceFileName1 = @ "File1.pdf" ; string sourceFileName2 = @ "File2.pdf" ; string sourceFileName3 = @ "File3.pdf" ; string destinationFileName = @ "Merged.pdf" ; // Merge 1 with (2, 3) and form destination PDFFile pdfFile = new PDFFile(sourceFileName1); pdfFile.MergeWith( new string [] { sourceFileName2, sourceFileName3}, destinationFileName); The output Merged.pdf will maintain the page sizes of each of the original pages from files 1, 2, and 3. See this link: https://www.leadtools.com/sdk/pdf You can also try LEADTOOLS virtual Document feature that allows you to merge documents regardless of the input type.
