How Do I Convert a URL to PDF with IronPDF?
This example shows IronPDF rendering a Wikipedia webpage into PDF using the RenderUrlAsPdf() method. This method requires an absolute URI pointing to the HTML document.
using IronPdf;
// Instantiate Renderer
var renderer = new ChromePdfRenderer();
// Create a PDF from a URL or local file path
var pdf = renderer.RenderUrlAsPdf("https://en.wikipedia.org/wiki/Main_Page");
// Export to a file or Stream
pdf.SaveAs("url.pdf");Imports IronPdf
' Instantiate Renderer
Private renderer = New ChromePdfRenderer()
' Create a PDF from a URL or local file path
Private pdf = renderer.RenderUrlAsPdf("https://en.wikipedia.org/wiki/Main_Page")
' Export to a file or Stream
pdf.SaveAs("url.pdf")The RenderUrlAsPdf method supports HTTP and HTTPS protocols. Before continuing, complete the Installation Overview to set up IronPDF in your development environment.
For complex scenarios, explore additional URL to PDF examples that demonstrate authentication, custom headers, and rendering options.
What Does the Generated PDF Look Like?
This is the file that the code produced:
Advanced Configuration with RenderingOptions
Customize your PDF conversion through the RenderingOptions property. Configure page margins, paper size, orientation, and more.
using IronPdf;
// Advanced renderer with custom options
var renderer = new ChromePdfRenderer();
// Configure rendering options
renderer.RenderingOptions.MarginTop = 40;
renderer.RenderingOptions.MarginBottom = 40;
renderer.RenderingOptions.CssMediaType = IronPdf.Rendering.PdfCssMediaType.Print;
renderer.RenderingOptions.PrintHtmlBackgrounds = true;
renderer.RenderingOptions.CreatePdfFormsFromHtml = true;
// Set custom paper size
renderer.RenderingOptions.PaperSize = IronPdf.Rendering.PdfPaperSize.A4;
renderer.RenderingOptions.PaperOrientation = IronPdf.Rendering.PdfPaperOrientation.Portrait;
// Render URL to PDF with custom settings
var pdf = renderer.RenderUrlAsPdf("https://example.com");
pdf.SaveAs("customized-output.pdf");Imports IronPdf
' Advanced renderer with custom options
Dim renderer As New ChromePdfRenderer()
' Configure rendering options
renderer.RenderingOptions.MarginTop = 40
renderer.RenderingOptions.MarginBottom = 40
renderer.RenderingOptions.CssMediaType = IronPdf.Rendering.PdfCssMediaType.Print
renderer.RenderingOptions.PrintHtmlBackgrounds = True
renderer.RenderingOptions.CreatePdfFormsFromHtml = True
' Set custom paper size
renderer.RenderingOptions.PaperSize = IronPdf.Rendering.PdfPaperSize.A4
renderer.RenderingOptions.PaperOrientation = IronPdf.Rendering.PdfPaperOrientation.Portrait
' Render URL to PDF with custom settings
Dim pdf = renderer.RenderUrlAsPdf("https://example.com")
pdf.SaveAs("customized-output.pdf")Handling JavaScript and Dynamic Content
Modern web pages rely on JavaScript to render content. IronPDF's Chrome rendering engine captures dynamic content through JavaScript rendering capabilities.
using IronPdf;
var renderer = new ChromePdfRenderer();
// Wait for JavaScript to execute
renderer.RenderingOptions.WaitFor.RenderDelay(2000); // Wait 2 seconds
// Or wait for specific JavaScript events
renderer.RenderingOptions.WaitFor.JavaScript(1500); // Maximum wait time
renderer.RenderingOptions.WaitFor.HtmlElement("div.dynamic-content", 5000);
var pdf = renderer.RenderUrlAsPdf("https://example.com/dynamic-page");
pdf.SaveAs("dynamic-content.pdf");Imports IronPdf
Dim renderer As New ChromePdfRenderer()
' Wait for JavaScript to execute
renderer.RenderingOptions.WaitFor.RenderDelay(2000) ' Wait 2 seconds
' Or wait for specific JavaScript events
renderer.RenderingOptions.WaitFor.JavaScript(1500) ' Maximum wait time
renderer.RenderingOptions.WaitFor.HtmlElement("div.dynamic-content", 5000)
Dim pdf = renderer.RenderUrlAsPdf("https://example.com/dynamic-page")
pdf.SaveAs("dynamic-content.pdf")My favorite library of this kind is IronPDF. It allows for fast and efficient manipulation of PDF files. It also has many valuable features, like exporting to PDF/A format and digitally signing PDF documents.
IronOCR means we can save $40,000 annually from manual processing, while enhancing productivity and freeing up resources for high-impact tasks. I would highly recommend it.
The IronSuite play a crucial role in our operations. These are tools that increase efficiencies across the business including creating floor plans and improving inventory management.
Adding Headers and Footers
Add headers and footers with page numbers, dates, or company information using IronPDF's Headers and Footers functionality.
using IronPdf;
var renderer = new ChromePdfRenderer();
// Add header with dynamic content
renderer.RenderingOptions.HtmlHeader = new HtmlHeaderFooter()
{
Height = 30,
HtmlFragment = "<div style='text-align:center;font-size:12px;'>{page} of {total-pages}</div>",
DrawDividerLine = true
};
// Add footer with company info
renderer.RenderingOptions.HtmlFooter = new HtmlHeaderFooter()
{
Height = 25,
HtmlFragment = "<div style='text-align:center;font-size:10px;'>© 2024 Your Company Name</div>",
DrawDividerLine = true
};
var pdf = renderer.RenderUrlAsPdf("https://example.com");
pdf.SaveAs("with-headers-footers.pdf");Imports IronPdf
Dim renderer = New ChromePdfRenderer()
' Add header with dynamic content
renderer.RenderingOptions.HtmlHeader = New HtmlHeaderFooter() With {
.Height = 30,
.HtmlFragment = "<div style='text-align:center;font-size:12px;'>{page} of {total-pages}</div>",
.DrawDividerLine = True
}
' Add footer with company info
renderer.RenderingOptions.HtmlFooter = New HtmlHeaderFooter() With {
.Height = 25,
.HtmlFragment = "<div style='text-align:center;font-size:10px;'>© 2024 Your Company Name</div>",
.DrawDividerLine = True
}
Dim pdf = renderer.RenderUrlAsPdf("https://example.com")
pdf.SaveAs("with-headers-footers.pdf")Optimizing CSS for PDF Output
