Append Page in PDF Doc using C# and .NET

Adding pages to PDF documents is an important task when working with PDF files. This may be necessary to create new documents, add content, or merge multiple PDF files. In this article, we will look at how to add a page to a PDF file using the library PDF.NET from SautinSoft.

SDK provides many additional features for working with PDF documents:

  • Setting page parameters: You can set the size, orientation and other page parameters.
  • Adding graphics and images: In addition to text, you can add graphics and images to pages.
  • Merging PDF files: You can combine multiple PDF files into one document.

    Step-by-step guide:

  1. Add SautinSoft.PDF from NuGet.
  2. Create a new PDF document.
  3. Add the first page with some formatting.
  4. Save the document.
