merge or combine PDFs | .NET PDF library

Overview

Syncfusion Essential PDF is a .NET PDF library that allows you to combine or merge different PDF files into one file. Merge PDF functionality can be used in any .NET application, whether it is Windows Forms, WPF, ASP.NET (Web Forms, MVC, Core), or even UWP, Xamarin.Forms, Xamarin.Android, and Xamarin.iOS. It will help you combine, import, and append PDFs with just a few lines of code using C# or VB.NET.

Merge PDFs

The Syncfusion .NET PDF library combines or merges different PDF files or pages to form a single document. It preserves the exact layout, form fields, annotations, bookmarks and appearance of the source files. Besides this process, developers can also create a new PDF with certain pages from the existing documents and also combine groups of PDF files from a specific directory or folder.

Combine multiple PDF files from disk and stream.
Import or insert pages from one PDF file to another.
Specify a range of pages to be merged from separate PDF documents.
Password-protect the combined PDF.
