Convert URL to PDF Example

Here we have an example of IronPDF rendering a Wikipedia webpage into PDF by using the RenderUrlAsPdf() method. The parameter is an absolute (fully formed) Uri. This points to the HTML document to be rendered as a PDF.

:path=/static-assets/pdf/content-code-examples/how-to/url-to-pdf.cs

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")
