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 IronPdf namespace with the using keyword
Create a new ChromePdfRenderer renderer
Call RenderHtmlAsPdf and then SaveAs on the result.

using IronPdf;

namespace IronPDFSample
{
    class Program
    {
        static void Main()
        {
            var Renderer = new ChromePdfRenderer();
            Renderer.RenderHtmlAsPdf("<h1>Hello World<h1>").SaveAs("html-string.pdf");
        }
    }
}

using IronPdf;

namespace IronPDFSample
{
    class Program
    {
        static void Main()
        {
            var Renderer = new ChromePdfRenderer();
            Renderer.RenderHtmlAsPdf("<h1>Hello World<h1>").SaveAs("html-string.pdf");
        }
    }
}

Imports IronPdf

Namespace IronPDFSample
	Friend Class Program
		Shared Sub Main()
			Dim Renderer = New ChromePdfRenderer()
			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#

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 ChromePdfRenderer();
            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 ChromePdfRenderer();
            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 ChromePdfRenderer()
			Dim PDF = Renderer.RenderUrlAsPdf("https://en.wikipedia.org/wiki/Portable_Document_Format")
			PDF.SaveAs("wikipedia.pdf")
		End Sub
	End Class
End Namespace

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 IronPdf namespace with the using keyword
Open the code-behind for the page that you want to render to PDF. For example, Default.aspx.cs
Call RenderThisPageAsPdf on 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 = IronPdf.ChromePdfRenderer.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 = IronPdf.ChromePdfRenderer.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 = IronPdf.ChromePdfRenderer.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 ChromePdfRenderer 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 ChromePdfRenderer = new ChromePdfRenderer();

            ChromePdfRenderer.RenderingOptions.FirstPageNumber = 1;

            //Header options
            ChromePdfRenderer.RenderingOptions.TextHeader.DrawDividerLine = true;
            ChromePdfRenderer.RenderingOptions.TextHeader.CenterText = "{url}";
            ChromePdfRenderer.RenderingOptions.TextHeader.FontFamily = "Helvetica,Arial";
            ChromePdfRenderer.RenderingOptions.TextHeader.FontSize = 12;

            //Footer options
            ChromePdfRenderer.RenderingOptions.TextFooter.DrawDividerLine = true;
            ChromePdfRenderer.RenderingOptions.TextFooter.FontFamily = "Arial";
            ChromePdfRenderer.RenderingOptions.TextFooter.FontSize = 10;
            ChromePdfRenderer.RenderingOptions.TextFooter.LeftText = "{date} {time}";
            ChromePdfRenderer.RenderingOptions.TextFooter.RightText = "{page} of {total-pages}";

            ChromePdfRenderer.RenderHtmlAsPdf("<h1>Hello World<h1>").SaveAs("html-string.pdf");
        }
    }
}

using IronPdf;

namespace ConsoleApp
{
    class Program
    {
        static void Main(string[] args)
        {
            var ChromePdfRenderer = new ChromePdfRenderer();

            ChromePdfRenderer.RenderingOptions.FirstPageNumber = 1;

            //Header options
            ChromePdfRenderer.RenderingOptions.TextHeader.DrawDividerLine = true;
            ChromePdfRenderer.RenderingOptions.TextHeader.CenterText = "{url}";
            ChromePdfRenderer.RenderingOptions.TextHeader.FontFamily = "Helvetica,Arial";
            ChromePdfRenderer.RenderingOptions.TextHeader.FontSize = 12;

            //Footer options
            ChromePdfRenderer.RenderingOptions.TextFooter.DrawDividerLine = true;
            ChromePdfRenderer.RenderingOptions.TextFooter.FontFamily = "Arial";
            ChromePdfRenderer.RenderingOptions.TextFooter.FontSize = 10;
            ChromePdfRenderer.RenderingOptions.TextFooter.LeftText = "{date} {time}";
            ChromePdfRenderer.RenderingOptions.TextFooter.RightText = "{page} of {total-pages}";

            ChromePdfRenderer.RenderHtmlAsPdf("<h1>Hello World<h1>").SaveAs("html-string.pdf");
        }
    }
}

Imports IronPdf

Namespace ConsoleApp
	Friend Class Program
		Shared Sub Main(ByVal args() As String)
			Dim ChromePdfRenderer As New ChromePdfRenderer()

			ChromePdfRenderer.RenderingOptions.FirstPageNumber = 1

			'Header options

			ChromePdfRenderer.RenderingOptions.TextFooter.RightText = "{page} of {total-pages}"

			ChromePdfRenderer.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 ChromePdfRenderer = new ChromePdfRenderer();

            // Build a footer using html to style the text // mergeable fields are: 
            // {page} {total-pages} {url} {date} {time} {html-title} & {pdf-title} 
            ChromePdfRenderer.RenderingOptions.HtmlFooter = 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
            ChromePdfRenderer.RenderingOptions.HtmlHeader = new HtmlHeaderFooter()
            {
                Height = 20,
                HtmlFragment = "<img src='logo.jpg'>",
                BaseUrl = new Uri(@"C:\assets\images").AbsoluteUri
            };

            ChromePdfRenderer.RenderHtmlAsPdf("<h1>Hello World<h1>").SaveAs("html-string.pdf");
        }
    }
}

using IronPdf;
using System;

namespace ConsoleApp
{
    class Program
    {
        static void Main(string[] args)
        {
            var ChromePdfRenderer = new ChromePdfRenderer();

            // Build a footer using html to style the text // mergeable fields are: 
            // {page} {total-pages} {url} {date} {time} {html-title} & {pdf-title} 
            ChromePdfRenderer.RenderingOptions.HtmlFooter = 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
            ChromePdfRenderer.RenderingOptions.HtmlHeader = new HtmlHeaderFooter()
            {
                Height = 20,
                HtmlFragment = "<img src='logo.jpg'>",
                BaseUrl = new Uri(@"C:\assets\images").AbsoluteUri
            };

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 ChromePdfRenderer = new ChromePdfRenderer();
            var pdfDocument = ChromePdfRenderer.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 ChromePdfRenderer = new ChromePdfRenderer();
            var pdfDocument = ChromePdfRenderer.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 ChromePdfRenderer As New ChromePdfRenderer()
			Dim pdfDocument = ChromePdfRenderer.RenderHtmlAsPdf("<h1>Hello World<h1>")
			pdfDocument.Password = "strong!@#pass&^%word"
			pdfDocument.SaveAs("secured.pdf")
		End Sub
	End Class
End Namespace

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 ChromePdfRenderer = new ChromePdfRenderer();
            //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(ChromePdfRenderer.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;

{
    class Program
    {
        static void Main(string[] args)
        {
            var ChromePdfRenderer = new ChromePdfRenderer();
            //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(ChromePdfRenderer.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");
        }
    }

10. Extract Images from PDF Documents

This feature requires an additional NuGet package. Install System.Drawing.Common. Use the ExtractAllText to get text and the ExtractAllImages method to get images.

using IronPdf;

namespace ConsoleApp
{
    class Program
    {
        static void Main(string[] args)
        {
            var ChromePdfRenderer = new ChromePdfRenderer();

            var pdfDocument = PdfDocument.FromFile("A.pdf");

            //Get all text
            var allText = pdfDocument.ExtractAllText();

            //Get all Images
            var allImages = pdfDocument.ExtractAllImages();

            //Or even find the images and text by page
            for (var index = 0; index < pdfDocument.PageCount; index++)

            //Or even find the images and text by page
            for (var index = 0; index < pdfDocument.PageCount; index++)
            {
                var pageNumber = index + 1;
                var pageText = pdfDocument.ExtractTextFromPage(index);
                var pageImages = pdfDocument.ExtractImagesFromPage(index);

12. PDF OCR and Text Extraction

In many cases you can extract embedded text from PDFs directly:

using IronPdf;

PdfDocument PDF = PdfDocument.FromFile("Invoice.pdf", "password");

//Get all text 
string Text = PDF.ExtractAllText();

using IronPdf;

PdfDocument PDF = PdfDocument.FromFile("Invoice.pdf", "password");

//Get all text 
string Text = PDF.ExtractAllText();

Imports IronPdf

Private PDF As PdfDocument = PdfDocument.FromFile("Invoice.pdf", "password")

'Get all text 
Private Text As String = PDF.ExtractAllText()

VB C#

If that doesnt work - your text is probably actually embedded in an image:

Use the IronOCR library to scan documents for visual text that is not plain text.

You will need to install the Nuget package IronOcr. Learn more about scanning PDFs with IronOCR.

using IronOcr;
using IronPdf;

namespace ConsoleApp
{
    class Program
    {
        static void Main(string[] args)
        {

           using (var Input = new OcrInput())
            {
                // OCR entire document
                Input.AddPdf("Invoice.pdf", "password");

                // Image Quality
                Input.Deskew();
                Input.DeNoise();
                var Result = Ocr.Read(Input);
                Console.WriteLine(Result.Text);

                var Barcodes = Result.Barcodes;
                var Text = Result.Text;
            }

        }
    }
}

using IronOcr;
using IronPdf;

namespace ConsoleApp
{
    class Program
    {
        static void Main(string[] args)
        {

           using (var Input = new OcrInput())
            {
                // OCR entire document
                Input.AddPdf("Invoice.pdf", "password");

                var Result = Ocr.Read(Input);
                Console.WriteLine(Result.Text);

                var Barcodes = Result.Barcodes;
                var Text = Result.Text;
