How to Add Stamps & Watermarks to PDFs in C#

In this tutorial, we explore how to stamp text, images, and HTML onto PDFs using IronPDF in a C# console application. Begin by installing IronPDF through the NuGet package manager. Set up your environment with an IronPDF license key, and use the Chrome PDF Renderer to generate a PDF from HTML content.

Create a TextStamper object to customize text properties like font, size, and alignment. For images, use an ImageStamper with specific alignment and offset settings. An HtmlStamper allows embedding HTML content into the PDF. Apply these stampers individually or simultaneously using the ApplyMultipleStamps method, and save the modified PDF using the SaveAs method. This approach streamlines the process, saving time and effort. Finally, the tutorial demonstrates how to run the program and check the output PDF with successfully applied stamps.
