IronPDF.Aspx has been designed for simple integration with existing c# and vb.net websites:

By calling the IronPDF.Aspx.RenderThisPageAsPDF method from inside the Page_Load event, the ASPX file automatically outputs a PDF instead of HTML

using IronPdf;

HtmlToPdf HtmlToPdf = new IronPdf.HtmlToPdf();
PdfResource PDF = HtmlToPdf.RenderUrlAsPdf(@"http://myurl.com");
PDF.SaveAs(@"Path\File.Pdf");

// or System.IO.MemoryStream PdfStream = PDF.GetStream;
// or byte[] PdfBinary = PDF.GetBinary;
using IronPdf;

HtmlToPdf HtmlToPdf = new IronPdf.HtmlToPdf();

HtmlToPdf.PrintOptions.Dpi = 300;
HtmlToPdf.PrintOptions.PDFPaperSize = PDFPrintOptions.PaperSize.A4;
HtmlToPdf.PrintOptions.EnableJavaScript = true;
HtmlToPdf.PrintOptions.AllowScreenCss = false;
HtmlToPdf.PrintOptions.Header = "{page} of {total-pages}";
HtmlToPdf.PrintOptions.GrayScale = false;
