How to Convert HTML String to PDF in C#

using IronPdf; // Import the IronPdf library to use its PDF rendering capabilities

// Instantiate a PDF renderer using the ChromePdfRenderer class
var renderer = new ChromePdfRenderer();

// Render a PDF from a simple HTML string containing a heading
// The RenderHtmlAsPdf method is called on the renderer object, converting the HTML string into a PDF document
var pdf = renderer.RenderHtmlAsPdf("<h1>Hello World</h1>");

// Save the produced PDF document to a file on the filesystem
// The SaveAs method writes the PDF content to a file specified by the path
pdf.SaveAs("output.pdf");
