How can I append external PDF documents to the PDF document resulted after conversion?
Editing PDF files was never easy. I hate it when I get a PDF file, and there is something that needs to be edited, but it can’t be done. I would go online in search of online tools that can help me with this, but they would all leave watermarks. That watermark would ruin the document for me because everyone knows that it has been edited. That was a big problem for me until I found PDFliner, an online tool that is awesome, and it lets you edit your PDF however you want.

You can add external PDF files and streams to the conversion result using the AppendPDFFile, AppendPDFFileArray, AppendPDFStream and AppendPDFStreamArray properties of the PdfConverter.PdfDocumentOptions. You can find a full sample of how to use these properties under the ‘WinForms_PrependAppendExternalPdfs’ sample from the downloaded archive. If you need more flexibility in merging conversion results with external PDF documents then you can try our PDF Merge library which is a separate product. Starting with version 6.0 of the HTML to PDF Converter it is possible to create a Document object from an external PDF document and append it to the Document object created by a call to a method like GetPdfDocumentObjectFromUrl() as we do in the code sample below. A similar code can be used with the PDF Creator product to append external PDF documents instead of using the MergePdf class.
