These rendering options give you precise control over paper size and orientation, margin settings for professional layouts, background color and image rendering, form field creation from HTML inputs, and CSS media type selection for print-improved styles. The CssMediaType.Print setting is particularly useful as it applies print-specific CSS rules, ensuring your generated PDF documents use appropriate styling for printed documents rather than screen display. Learn more about rendering options in the documentation. You can also explore grayscale conversion, page breaks, and base URLs for advanced configurations.

How Can I Convert Web Pages to PDF?

Converting web pages to PDF is one of IronPDF's most effective features. Whether you need to archive web content, create reports from online dashboards, or generate PDFs from your application's pages, IronPDF handles it all. The URL to PDF conversion guide provides detailed instructions:

using IronPdf;
// Create a new ChromePdfRenderer instance
var renderer = new ChromePdfRenderer();
// Configure custom rendering options for rendering a web page
renderer.RenderingOptions.EnableJavaScript = true;
renderer.RenderingOptions.WaitFor.JavaScript(3000); // Wait an additional 3 seconds for JavaScript to load
renderer.RenderingOptions.CssMediaType = IronPdf.Rendering.PdfCssMediaType.Print;
// Convert any public webpage to PDF
var pdf = renderer.RenderUrlAsPdf("___PROTECTED_URL_113___");
pdf.SaveAs("reddit-homepage.pdf");

using IronPdf;
// Create a new ChromePdfRenderer instance
var renderer = new ChromePdfRenderer();
// Configure custom rendering options for rendering a web page
renderer.RenderingOptions.EnableJavaScript = true;
renderer.RenderingOptions.WaitFor.JavaScript(3000); // Wait an additional 3 seconds for JavaScript to load
renderer.RenderingOptions.CssMediaType = IronPdf.Rendering.PdfCssMediaType.Print;
// Convert any public webpage to PDF
var pdf = renderer.RenderUrlAsPdf("___PROTECTED_URL_113___");
pdf.SaveAs("reddit-homepage.pdf");

$vbLabelText $csharpLabel

IronPDF simplifies generating pixel-perfect PDF documents from URL content in just a few lines of code. The RenderUrlAsPdf method goes to the specified URL, waits for the page to fully load, executes any JavaScript on the page, and then captures the rendered output as a PDF. This process uses a real Chrome browser engine, ensuring perfect fidelity with the original webpage. You can also handle authentication for secured pages and add cookies for session management.

How Do I Handle Local Files and Resources?

IronPDF can also convert local HTML files, making it perfect for generating PDFs from templates. The library also supports HTML ZIP files for complex projects:

using IronPdf;
var renderer = new ChromePdfRenderer();
// Render a local HTML file
string filename = "report-template.html";
var pdf = renderer.RenderHtmlFileAsPdf(filename);
pdf.SaveAs("report.pdf");

using IronPdf;
var renderer = new ChromePdfRenderer();
// Render a local HTML file
string filename = "report-template.html";
var pdf = renderer.RenderHtmlFileAsPdf(filename);
pdf.SaveAs("report.pdf");

$vbLabelText $csharpLabel

The BaseUrl setting tells IronPDF where to find resources referenced in your HTML, such as images, CSS files, and JavaScript libraries. This approach works perfectly for template-based PDF generation, where you have pre-designed HTML templates that get populated with dynamic data. You can embed images with DataURIs or reference Azure Blob Storage for cloud-based assets.

How Do I Handle JavaScript-Heavy Content?

Modern web applications rely heavily on JavaScript for dynamic content generation. IronPDF excels at handling these scenarios when you need to generate PDF documents from JavaScript-rich pages. The JavaScript to PDF guide provides complete coverage:

using IronPdf;
var renderer = new ChromePdfRenderer();
// Configure JavaScript rendering for PDF generation
renderer.RenderingOptions.EnableJavaScript = true;
renderer.RenderingOptions.WaitFor.RenderDelay(2000); // Wait 2 seconds for JS to execute
// Convert a JavaScript-heavy page to PDF
var htmlFile = "TestFiles\\JS-example.html";
var pdf = renderer.RenderHtmlFileAsPdf(htmlFile);
pdf.SaveAs("javascript-example.pdf");

using IronPdf;
var renderer = new ChromePdfRenderer();
// Configure JavaScript rendering for PDF generation
renderer.RenderingOptions.EnableJavaScript = true;
renderer.RenderingOptions.WaitFor.RenderDelay(2000); // Wait 2 seconds for JS to execute
// Convert a JavaScript-heavy page to PDF
var htmlFile = "TestFiles\\JS-example.html";
var pdf = renderer.RenderHtmlFileAsPdf(htmlFile);
pdf.SaveAs("javascript-example.pdf");

$vbLabelText $csharpLabel

This example demonstrates how IronPDF handles JavaScript-heavy content when generating PDFs in .NET. By enabling EnableJavaScript and adding a short RenderDelay, the ChromePdfRenderer waits for dynamic scripts, such as charts and animations, to finish executing before capturing the PDF. Here, we render a local HTML file (JS-example.html) and save it as javascript-example.pdf, ensuring the final PDF reflects all the interactive and dynamically generated content exactly as it appears in a browser. The WaitFor options provide precise control over rendering timing.

IronPDF supports all modern JavaScript frameworks and libraries. Whether your application uses React, Angular, Vue.js, or vanilla JavaScript, the Chrome rendering engine executes everything precisely as it would in a standard browser. Charts render perfectly, dynamic forms maintain their state, and single-page applications display their routed content correctly. For more details on handling JavaScript, see the JavaScript to PDF guide. You can also render WebGL sites and handle custom JavaScript execution.

How Do I Handle Authentication and Secured Pages?

Many applications require authentication to access certain pages. IronPDF provides several mechanisms for handling secured content through TLS website logins and HTTP request headers:

using IronPdf;
var renderer = new ChromePdfRenderer();
ChromePdfRenderer renderer = new ChromePdfRenderer
{
    // setting login credentials to bypass basic authentication
    LoginCredentials = new ChromeHttpLoginCredentials()
