How to Combine PDF Documents

The following steps illustrate combining multiple PDF documents into a single PDF.

Steps for Combining PDF Documents

1. Create a MergeDocument object by passing the first PDF file to the constructor.
2. Call the Append method with the second PDF document.
3. Call the Append method a third time to append another PDF document. Also pass the 1, and 2 page parameters to the Append method.
4. Call the Draw method to save the merged PDF.

The Append method has several overloaded methods, including specifying the start page and page count properties. For example, the Append method below appends two pages of the document DocumentC.pdf, beginning with page one. For more information on the options available to you using Append, refer to the MergeDoccument.Append documentation.

Sample Code - C#

MergeDocument document = new MergeDocument("DocumentA.pdf");
document.Append("DocumentB.pdf);
document.Append("DocumentC.pdf, 1, 2);
document.Draw("Output.pdf");

Steps for Specifying MergeOptions for PDF Document

1. Create a MergeOptions object by calling the static Append method.
2. Set the MergeOptions Outlines to false.
3. Create a new MergeDocument.
4. Call the Append method to append a document. Also pass options to the Append method.
5. Call the Draw method to save the merged PDF.

As mentioned above, the Append method has several overloaded methods available for you to use. In this example, you use the MergeOptions class combined with the Outlines property to specify that the PDF's outlines and bookmarks are not imported. Refer to the MergeOptions documentation for more information.

Sample Code - C#

MergeOptions options = MergeOptions.Append;
options.Outlines = false;
MergeDocument document = new MergeDocument();
document.Append("DocumentC.pdf", options);
document.Draw("Output.pdf");
