In this tutorial, we explore the process of stamping barcodes on PDF files using IronBarcode. To begin, ensure IronBarcode is installed on your machine. The process starts by importing the IronBarcode namespace and utilizing the CreateBarcode method, which requires the content, encoding type, and dimensions for the barcode. In this example, a URL is encoded into a 100x100 pixel QR code.

Next, specify the PDF pages to be modified by creating a list of integers. Use the StampToExistingPdfPages method to apply the barcode. This involves providing the PDF path, X and Y coordinates for placement, and pages for modification, with an optional password for protected files. Running the program applies the barcode to the defined pages, as demonstrated in the output PDF. The QR code, when scanned, redirects to the encoded URL. The tutorial concludes by inviting viewers to try a 30-day trial of the software for firsthand experience.
