How to Add PDF Bookmarks and Outlines in C# Using IronPDF

In this tutorial, we explore adding bookmarks and outlines to PDF files using IronPDF in C#. After setting up IronPDF with the NuGet Package Manager, we delve into the Program.cs file, importing the necessary namespace and inputting the IronPDF license key.

We load an existing PDF with the FromFile method, ensuring to replace the file path with your own PDF. A main bookmark titled 'examination' is created with sub-bookmarks for specific dates and test types, and further bookmarks are added for individuals who took tests on those dates. This process is repeated for subsequent dates. Finally, the newly bookmarked PDF is saved as 'multi-layer bookmarks PDF'. Upon execution, this PDF allows users to navigate directly to specific pages via bookmarks, which is particularly useful for managing large, complex documents. This tutorial offers a practical approach to enhancing PDF navigation using IronPDF, providing clear steps and encouraging users to explore the software's capabilities further.
