Unlock the power of efficient PDF management in C# by watching our step-by-step tutorial on merging and splitting PDFs with IronPDF, and take your document handling skills to the next level!

In this tutorial, we explore how to merge and split PDF files using IronPDF in C#. The process begins with installing IronPDF via the NuGet package manager. After importing the IronPDF namespace, we define HTML strings representing PDF pages. Using a Chrome PDF Renderer, we render these strings into two separate PDF documents. We then merge these documents with the PDFDocument.Merge method, saving the result as a merged file. Additionally, we extract individual pages using the CopyPage method, saving them as separate PDF files. The tutorial provides a step-by-step demonstration, concluding with a successful execution of the program, showcasing the merged and split PDFs. Users are encouraged to try IronPDF with a trial link provided in the description.
