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.
