Renderer.RenderHtmlAsPdf("<h1>Hello World<h1>").SaveAs("html-string.pdf");
Imports IronPdf

Private Renderer As New IronPdf.HtmlToPdf()
Renderer.RenderHtmlAsPdf("<h1>Hello World<h1>").SaveAs("html-string.pdf")
VB   C#

HTML File to PDF Example

HTML files with images, CSS, forms, hyperlinks and even JavaScript may be rendered into PDF documents.

using IronPdf;

// Create a PDF from an existing HTML using C#
 var Renderer = new IronPdf.HtmlToPdf();
 var PDF = Renderer.RenderHTMLFileAsPdf("Assets/MyHTML.html");
 PDF.SaveAs("MyPdf.pdf");

Imports IronPdf

' Create a PDF from an existing HTML using C#
 Private Renderer = New IronPdf.HtmlToPdf()
 Private PDF = Renderer.RenderHTMLFileAsPdf("Assets/MyHTML.html")
 PDF.SaveAs("MyPdf.pdf")
VB   C#

URL to PDF Example

Existing web pages may also be rendered as PDFs in a few lines of C# or VB.Net code

using IronPdf;

// Create a PDF from any existing web page
var Renderer = new IronPdf.HtmlToPdf();
var PDF = Renderer.RenderUrlAsPdf("https://en.wikipedia.org/wiki/Portable_Document_Format");
PDF.SaveAs("wikipedia.pdf");

Imports IronPdf

protected void Page_Load(object sender, EventArgs e)
{
    IronPdf.AspxToPdf.RenderThisPageAsPdf(IronPdf.AspxToPdf.FileBehavior.InBrowser);
}
Protected Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs)
	IronPdf.AspxToPdf.RenderThisPageAsPdf(IronPdf.AspxToPdf.FileBehavior.InBrowser)
End Sub
