2. Render HTML String to PDF
IronPDF can render HTML text to PDF quite easily. This example illustrates the capability. Use this option when you only need to add simple text to your PDF document.
- Create a new .NET Core console application
- Install the NuGet package
- Import the
IronPdfnamespace with theusingkeyword - Create a new
HtmlToPdfrenderer - Call
RenderHtmlAsPdfand thenSaveAson the result.
using IronPdf;
namespace IronPDFSample
{
class Program
{
static void Main()
{
var Renderer = new HtmlToPdf();
Renderer.RenderHtmlAsPdf("<h1>Hello World<h1>").SaveAs("html-string.pdf");
}
}
}
using IronPdf;
namespace IronPDFSample
{
class Program
{
static void Main()
{
var Renderer = new HtmlToPdf();
Renderer.RenderHtmlAsPdf("<h1>Hello World<h1>").SaveAs("html-string.pdf");
}
}
}
Imports IronPdf
Namespace IronPDFSample
Friend Class Program
Shared Sub Main()
Dim Renderer = New HtmlToPdf()
Renderer.RenderHtmlAsPdf("<h1>Hello World<h1>").SaveAs("html-string.pdf")
End Sub
End Class
End Namespace VB C#
3. Convert HTML File to PDF
You can render HTML files with images, CSS, forms, hyperlinks, and JavaScript as a PDF document. Use this method for scenarios where you have access to the source document locally.
This example calls RenderHTMLFileAsPdf, which returns a variable called PDF.
Call SaveAs to save the output to a PDF file.
The sample assumes that there is a HTML file in the folder Assets.
using IronPdf;
namespace IronPDFSample
{
class Program
{
static void Main()
{
// Create a PDF from an existing HTML using C#
var Renderer = new HtmlToPdf();
var PDF = Renderer.RenderHTMLFileAsPdf("Assets/MyHTML.html");
PDF.SaveAs("MyPdf.pdf");
}
}
}using IronPdf;
namespace IronPDFSample
{
class Program
{
static void Main()
{
// Create a PDF from an existing HTML using C#
var Renderer = new HtmlToPdf();
var PDF = Renderer.RenderHTMLFileAsPdf("Assets/MyHTML.html");
PDF.SaveAs("MyPdf.pdf");
}
}
}Imports IronPdf
Namespace IronPDFSample
Friend Class Program
Shared Sub Main()
' Create a PDF from an existing HTML using C#
Dim Renderer = New HtmlToPdf()
Dim PDF = Renderer.RenderHTMLFileAsPdf("Assets/MyHTML.html")
PDF.SaveAs("MyPdf.pdf")
End Sub
End Class
End Namespace VB C#
4. Render Existing URL to PDF
Render existing web pages to PDFs in a few lines of C# or VB.Net code. Use this option when you need to convert a website that already has a well-formatted document to a PDF.
Call the RenderUrlAsPdf to download web page content so that you can call SaveAs to export the content locally.
using IronPdf;
namespace IronPDFSample
{
class Program
{
static void Main()
{
// Create a PDF from any existing web page
var Renderer = new HtmlToPdf();
var PDF = Renderer.RenderUrlAsPdf("https://en.wikipedia.org/wiki/Portable_Document_Format");
PDF.SaveAs("wikipedia.pdf");
}
}
}using IronPdf;
namespace IronPDFSample
{
class Program
{
static void Main()
{
// Create a PDF from any existing web page
var Renderer = new HtmlToPdf();
var PDF = Renderer.RenderUrlAsPdf("https://en.wikipedia.org/wiki/Portable_Document_Format");
PDF.SaveAs("wikipedia.pdf");
}
}
}Imports IronPdf
Namespace IronPDFSample
Friend Class Program
Shared Sub Main()
' Create a PDF from any existing web page
Dim Renderer = New HtmlToPdf()
Dim PDF = Renderer.RenderUrlAsPdf("https://en.wikipedia.org/wiki/Portable_Document_Format")
PDF.SaveAs("wikipedia.pdf")
End Sub
End Class
End Namespace VB C#
5. ASP.NET Web Forms to PDF
Render ASP.NET web forms as PDF instead of HTML with a single line of code. Place the line of code in the Page_Load method of the page's code-behind.
- Create a new ASP.NET WebForms application or open an existing one
- Install the NuGet package
- Import the
IronPdfnamespace with theusingkeyword - Open the code-behind for the page that you want to render to PDF. For example,
Default.aspx.cs - Call
RenderThisPageAsPdfon AspxToPdf
using IronPdf;
using System;
using System.Web.UI;
namespace WebApplication7
{
public partial class _Default : Page
{
protected void Page_Load(object sender, EventArgs e)
{ AspxToPdf.RenderThisPageAsPdf(AspxToPdf.FileBehavior.InBrowser);
}
}
}using IronPdf;
using System;
using System.Web.UI;
namespace WebApplication7
{
public partial class _Default : Page
{
protected void Page_Load(object sender, EventArgs e)
{ AspxToPdf.RenderThisPageAsPdf(AspxToPdf.FileBehavior.InBrowser);
}
}
}Imports IronPdf
Imports System
Imports System.Web.UI
Namespace WebApplication7
Partial Public Class _Default
Inherits Page
Protected Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs)
AspxToPdf.RenderThisPageAsPdf(AspxToPdf.FileBehavior.InBrowser)
End Sub
End Class
End Namespace VB C#
6. Route ASP MVC View to PDF
Route the user to a PDF document with the ASP MVC framework. Use this option when creating a new ASP MVC app or add an existing MVC controller to an app.
Start the new project wizard in Visual Studio, and choose ASP.NET Web Application (.NET Framework) -> MVC. Or open an existing MVC project. Open the file HomeController in the Controllers folder and replace the Index method, or add a new controller.
This is an example of how the code should look:
using IronPdf;
using System;
using System.Web.Mvc;
namespace WebApplication8.Controllers
{
public class HomeController : Controller
{
public ActionResult Index()
{
var PDF = HtmlToPdf.StaticRenderUrlAsPdf(new Uri("https://en.wikipedia.org"));
return File(PDF.BinaryData, "application/pdf", "Wiki.Pdf");
}
public ActionResult About()
{
ViewBag.Message = "Your application description page.";
return View();
}
public ActionResult Contact()
{
ViewBag.Message = "Your contact page.";
return View();
}
}
}using IronPdf;
using System;
using System.Web.Mvc;
namespace WebApplication8.Controllers
{
public class HomeController : Controller
{
public ActionResult Index()
{
var PDF = HtmlToPdf.StaticRenderUrlAsPdf(new Uri("https://en.wikipedia.org"));
return File(PDF.BinaryData, "application/pdf", "Wiki.Pdf");
}
public ActionResult About()
{
ViewBag.Message = "Your application description page.";
return View();
}
public ActionResult Contact()
{
ViewBag.Message = "Your contact page.";
return View();
}
}
}Imports IronPdf
Imports System
Imports System.Web.Mvc
Namespace WebApplication8.Controllers
Public Class HomeController
Inherits Controller
Public Function Index() As ActionResult
Dim PDF = HtmlToPdf.StaticRenderUrlAsPdf(New Uri("https://en.wikipedia.org"))
Return File(PDF.BinaryData, "application/pdf", "Wiki.Pdf")
End Function
Public Function About() As ActionResult
ViewBag.Message = "Your application description page."
Return View()
End Function
Public Function Contact() As ActionResult
ViewBag.Message = "Your contact page."
Return View()
End Function
End Class
End Namespace VB C#
7. Add Headers and Footers
The PrintOptions property allows you to craft headers and footers for each page of the document. Access these options on the HtmlToPdf object. This sample works inside a .NET Core console app.
Use these template properties to build the content.
{page} {total-pages} {url} {date} {time} {html-title} & {pdf-title}
using IronPdf;
namespace ConsoleApp
{
class Program
{
static void Main(string[] args)
{
var htmlToPdf = new HtmlToPdf();
htmlToPdf.PrintOptions.FirstPageNumber = 1;
//Header options
htmlToPdf.PrintOptions.Header.DrawDividerLine = true;
htmlToPdf.PrintOptions.Header.CenterText = "{url}";
htmlToPdf.PrintOptions.Header.FontFamily = "Helvetica,Arial";
htmlToPdf.PrintOptions.Header.FontSize = 12;
//Footer options
htmlToPdf.PrintOptions.Footer.DrawDividerLine = true;
htmlToPdf.PrintOptions.Footer.FontFamily = "Arial";
htmlToPdf.PrintOptions.Footer.FontSize = 10;
htmlToPdf.PrintOptions.Footer.LeftText = "{date} {time}";
htmlToPdf.PrintOptions.Footer.RightText = "{page} of {total-pages}";
htmlToPdf.RenderHtmlAsPdf("<h1>Hello World<h1>").SaveAs("html-string.pdf");
}
}
}using IronPdf;
namespace ConsoleApp
{
class Program
{
static void Main(string[] args)
{
var htmlToPdf = new HtmlToPdf();
htmlToPdf.PrintOptions.FirstPageNumber = 1;
//Header options
htmlToPdf.PrintOptions.Header.DrawDividerLine = true;
htmlToPdf.PrintOptions.Header.CenterText = "{url}";
htmlToPdf.PrintOptions.Header.FontFamily = "Helvetica,Arial";
htmlToPdf.PrintOptions.Header.FontSize = 12;
//Footer options
htmlToPdf.PrintOptions.Footer.DrawDividerLine = true;
htmlToPdf.PrintOptions.Footer.FontFamily = "Arial";
htmlToPdf.PrintOptions.Footer.FontSize = 10;
htmlToPdf.PrintOptions.Footer.LeftText = "{date} {time}";
htmlToPdf.PrintOptions.Footer.RightText = "{page} of {total-pages}";
htmlToPdf.RenderHtmlAsPdf("<h1>Hello World<h1>").SaveAs("html-string.pdf");
}
}
}Imports IronPdf
Namespace ConsoleApp
Friend Class Program
Shared Sub Main(ByVal args() As String)
Dim htmlToPdf As New HtmlToPdf()
htmlToPdf.PrintOptions.FirstPageNumber = 1
'Header options
htmlToPdf.PrintOptions.Header.DrawDividerLine = True
htmlToPdf.PrintOptions.Header.CenterText = "{url}"
htmlToPdf.PrintOptions.Header.FontFamily = "Helvetica,Arial"
htmlToPdf.PrintOptions.Header.FontSize = 12
'Footer options
htmlToPdf.PrintOptions.Footer.DrawDividerLine = True
htmlToPdf.PrintOptions.Footer.FontFamily = "Arial"
htmlToPdf.PrintOptions.Footer.FontSize = 10
htmlToPdf.PrintOptions.Footer.LeftText = "{date} {time}"
htmlToPdf.PrintOptions.Footer.RightText = "{page} of {total-pages}"
htmlToPdf.RenderHtmlAsPdf("<h1>Hello World<h1>").SaveAs("html-string.pdf")
End Sub
End Class
End Namespace VB C#
7.1. Add Headers and Footers with HTML
As above, this sample works in a .NET Core console app. Specify HTML with the HtmlFragment property.
using IronPdf;
using System;
namespace ConsoleApp
{
class Program
{
static void Main(string[] args)
{
var htmlToPdf = new HtmlToPdf();
// Build a footer using html to style the text // mergeable fields are:
// {page} {total-pages} {url} {date} {time} {html-title} & {pdf-title}
htmlToPdf.PrintOptions.Footer = new HtmlHeaderFooter()
{
Height = 15,
HtmlFragment = "<center><i>{page} of {total-pages}<i></center>",
DrawDividerLine = true
};
// Build a header using an image asset
// Note the use of BaseUrl to set a relative path to the assets
htmlToPdf.PrintOptions.Header = new HtmlHeaderFooter()
{
Height = 20,
HtmlFragment = "<img src='logo.jpg'>",
BaseUrl = new Uri(@"C:\assets\images").AbsoluteUri
};
htmlToPdf.RenderHtmlAsPdf("<h1>Hello World<h1>").SaveAs("html-string.pdf");
}
}
}using IronPdf;
using System;
namespace ConsoleApp
{
class Program
{
static void Main(string[] args)
{
var htmlToPdf = new HtmlToPdf();
// Build a footer using html to style the text // mergeable fields are:
// {page} {total-pages} {url} {date} {time} {html-title} & {pdf-title}
htmlToPdf.PrintOptions.Footer = new HtmlHeaderFooter()
{
Height = 15,
HtmlFragment = "<center><i>{page} of {total-pages}<i></center>",
DrawDividerLine = true
};
// Build a header using an image asset
// Note the use of BaseUrl to set a relative path to the assets
htmlToPdf.PrintOptions.Header = new HtmlHeaderFooter()
{
Height = 20,
HtmlFragment = "<img src='logo.jpg'>",
BaseUrl = new Uri(@"C:\assets\images").AbsoluteUri
};
htmlToPdf.RenderHtmlAsPdf("<h1>Hello World<h1>").SaveAs("html-string.pdf");
}
}
}Imports IronPdf
Imports System
Namespace ConsoleApp
Friend Class Program
Shared Sub Main(ByVal args() As String)
Dim htmlToPdf As New HtmlToPdf()
' Build a footer using html to style the text // mergeable fields are:
' {page} {total-pages} {url} {date} {time} {html-title} & {pdf-title}
htmlToPdf.PrintOptions.Footer = New HtmlHeaderFooter() With {
.Height = 15,
.HtmlFragment = "<center><i>{page} of {total-pages}<i></center>",
.DrawDividerLine = True
}
' Build a header using an image asset
' Note the use of BaseUrl to set a relative path to the assets
htmlToPdf.PrintOptions.Header = New HtmlHeaderFooter() With {
.Height = 20,
.HtmlFragment = "<img src='logo.jpg'>",
.BaseUrl = (New Uri("C:\assets\images")).AbsoluteUri
}
htmlToPdf.RenderHtmlAsPdf("<h1>Hello World<h1>").SaveAs("html-string.pdf")
End Sub
End Class
End Namespace VB C#
8. Encrypt PDFs with a Password
Set the Password property of a PDF document to encrypt it and force the user to enter the correct password to view the document. This sample works in a .NET Core Console app
using IronPdf;
namespace ConsoleApp
{
class Program
{
static void Main(string[] args)
{
var htmlToPdf = new HtmlToPdf();
var pdfDocument = htmlToPdf.RenderHtmlAsPdf("<h1>Hello World<h1>");
pdfDocument.Password = "strong!@#pass&^%word";
pdfDocument.SaveAs("secured.pdf");
}
}
}using IronPdf;
namespace ConsoleApp
{
class Program
{
static void Main(string[] args)
{
var htmlToPdf = new HtmlToPdf();
var pdfDocument = htmlToPdf.RenderHtmlAsPdf("<h1>Hello World<h1>");
pdfDocument.Password = "strong!@#pass&^%word";
pdfDocument.SaveAs("secured.pdf");
}
}
}Imports IronPdf
Namespace ConsoleApp
Friend Class Program
Shared Sub Main(ByVal args() As String)
Dim htmlToPdf As New HtmlToPdf()
Dim pdfDocument = htmlToPdf.RenderHtmlAsPdf("<h1>Hello World<h1>")
pdfDocument.Password = "strong!@#pass&^%word"
pdfDocument.SaveAs("secured.pdf")
End Sub
End Class
End Namespace VB C#
9. Merge and Split PDF Documents
Use the Merge method to merge multiple PDF documents together, or CopyPages to split a number of pages out of an existing document. Include PDFs in your project as Content to access them by filename.
using IronPdf;
using System.Collections.Generic;
namespace ConsoleApp
{
class Program
{
static void Main(string[] args)
{
var htmlToPdf = new HtmlToPdf();
//Join Multiple Existing PDFs into a single document
var pdfDocuments = new List<PdfDocument>();
pdfDocuments.Add(PdfDocument.FromFile("A.pdf"));
pdfDocuments.Add(PdfDocument.FromFile("B.pdf"));
pdfDocuments.Add(PdfDocument.FromFile("C.pdf"));
var mergedPdfDocument = PdfDocument.Merge(pdfDocuments);
mergedPdfDocument.SaveAs("merged.pdf");
//Add a cover page
mergedPdfDocument.PrependPdf(htmlToPdf.RenderHtmlAsPdf("<h1>Cover Page</h1><hr>"));
//Remove the last page from the PDF and save again
mergedPdfDocument.RemovePage(mergedPdfDocument.PageCount - 1);
mergedPdfDocument.SaveAs("merged.pdf");
//Copy pages 1,2 and save them as a new document.
mergedPdfDocument.CopyPages(1, 2).SaveAs("exerpt.pdf");
}
}
}using IronPdf;
using System.Collections.Generic;
namespace ConsoleApp
{
class Program
{
