What is IronPdf ?¶

Developer Notice: The Iron PDF Home Page Has Moved.¶

IronPDF is a commercial Grade PDF Generation library for the .Net platform, written in C#.

The key concept is to avoid time-consuming PDF generation APIs by rendering PDFs from HTML, CSS, Images and JavaScript.

IronPDF’s core features are:

Generating PDF documents from HTML as a string
Generating PDF documents from Urls
Rendering ASPX webforms as PDF documents on-the-fly

The base requirements are .Net framework 4.0 on the windows platform.

It works equally well in Forms Applications, Server Applications and Services, Web Applications, Secure Intranets, Console Apps, WPF Apps and MVC patterned websites.

QuickStart¶

Developer Notice: The Dot Net PDF QuickStart Guide Has Moved.¶

Get IronPdf Installed¶

Using Nuget Package manager in Visual Studio

PM> Install-Package IronPdf

Or Download IronPdf as DLL

Get http://localhost/iron/packages/IronPdf.zip
Add IronPdf.dll to your project as a reference or to the GAC.
Lazy option - just copy the dll into your /Bin folder in .net web applications.

Basic Usage¶

HTML String to Pdf¶

using IronPdf;

HtmlToPdf HtmlToPdf = new IronPdf.HtmlToPdf();
HtmlToPdf.RenderHtmlAsPdf("<p>html</p>"").SaveAs(@"Path\File.Pdf");

Url to Pdf¶

using IronPdf;

HtmlToPdf HtmlToPdf = new IronPdf.HtmlToPdf();
HtmlToPdf.RenderUrlAsPdf(@“http://myurl.com").SaveAs(@"Path\File.Pdf");

Advanced usage - you can also pass a System.Net.WebClient to RenderUrlAsPdf.

//...
HtmlToPdf.RenderUrlAsPdf("http://ironpdf.com", myWebClient ).SaveAs("File.Pdf");

This allows you to set login credentials, proxy settings, special headers, cookies - to log in to protected / secure web pages.

Pdf Settings¶

using IronPdf;

HtmlToPdf HtmlToPdf = new IronPdf.HtmlToPdf();

HtmlToPdf.PrintOptions.Dpi = 300;
HtmlToPdf.PrintOptions.PDFPaperSize = System.Drawing.PaperKind.A4;
HtmlToPdf.PrintOptions.EnableJavaScript = true;
HtmlToPdf.PrintOptions.AllowScreenCss = false;
HtmlToPdf.PrintOptions.SetHeaderText = "{page} of {total-pages}";
HtmlToPdf.PrintOptions.GrayScale = true;

You can also create a reusable instance of IronPDF.PdfPrintOptions and use it in the IronPdf.HtmlToPdf constructor.

AspxToPdf¶

Changes any ASPX web page to automatically render as a Pdf document instead of html.

using IronPdf;

private void Form1_Load(object sender, EventArgs e)
{
 //..
AspxToPdf.RenderThisPageAsPDF();
}

AspxToPdf with Advanced Settings

IronPdf.AspxToPdf.RenderThisPageAsPDF(AspxToPdf.FileBehaviour.Attachment, "MyPdfDownload.pdf", new PdfPrintOptions(){ Dpi = 300});

Pdf Outputs¶

HtmlToPdf.RenderUrlAsPdf and HtmlToPdf.RenderHtmlAsPdf return an instance of the IronPdf.PdfResource class.

In the above examples, we directly save each PDF as a file.

It is also possible to get the Pdf document as a System.IO.MemoryStream or a byte array (byte[])the Stream and BinaryData properties of PdfResource respectively.

using IronPdf;
HtmlToPdf HtmlToPdf = new IronPdf.HtmlToPdf();
//..
System.IO.MemoryStream stream = HtmlToPdf.RenderHtmlAsPdf("<p>html</p>).Stream;
//or
byte[] data = HtmlToPdf.RenderHtmlAsPdf("<p>html</p>"").BinaryData;

PdfPrintOptions IronPdf.HtmlToPdf.PrintOptions: Sets PDF output options such as Paper-Size, Dpi, Headers and Footers

IronPdf.AspxToPdf¶

AspxToPdf is a static class used to turn any ASPX web form into a PDF. The look and feel remain the same - but the output becomes a PDF.

This is simply achieved by adding AspxToPdf in your ASPX page code-behind. Normally this is a file named like Default.aspx.cs.

Just call IronPdf.AspxToPdf.RenderThisPageAsPdf() in your of your ASPX Form onLoad event.

Examples¶

Basic Example

private void Form1_Load(object sender, EventArgs e)
     {
          //..
          IronPdf.AspxToPdf.RenderThisPageAsPDF();
      }

Advanced Example

using IronPdf;

private void Form1_Load(object sender, EventArgs e)
    {
    //..

    var PrintOptions = new PdfPrintOptions(){ Dpi=100 };
    PrintOptions.SetHeaderText("{page} of {total-pages}”);

    AspxToPdf.RenderThisPageAsPDF(AspxToPdf.FileBehaviour.Attachment, "FileName.pdf", PrintOptions);

    }

IronPdf.AspxToPdf Reference¶

class

Renders any .Net Web Page (ASPX) into a PDF Document. Simply add it to the Page_Load event.

Example: protected void Page_Load(object sender, EventArgs e){ IronPdf.AspxToPdf.RenderThisPageAsPDF(); }

Public Types

enum type IronPdf::AspxToPdf::FileBehaviour¶

Determines the requested user web browser behavior towards the PDF: Downdload (Attachment) or display InBrowser (where plugin available).

Values:

Public Static Functions

static void IronPdf.AspxToPdf.RenderThisPageAsPDF(FileBehaviour PDFBehaviour, String PdfFileName, PdfPrintOptions PrintOptions)

Automagically renders any ASPX page into PDF instead of HTML. Use it in the Page_Load Event.

Example: protected void Page_Load(object sender, EventArgs e){ IronPdf.AspxToPdf.RenderThisPageAsPDF(FileBehaviour.Attachment, "MyPdf.pdf", new PdfPrintOptions(){ Dpi = 300 }); }

Parameters

PDFBehaviour -
Specifies if the PDF file should be downloaded as an attachment, or displayed directly in the browser (if an pdf browser plug-in is present).
PdfFileName -
The file-name of the PDF. If no name is set - a suitable name will be automatically assigned chosen based on the HTML title, PrintOptions or name of the ASPX page.
PrintOptions -
Sets PDF output options such as Pdf Title, Paper-Size, Dpi, Headers and Footers

IronPdf.PdfPrintOptions¶

PdfPrintOptions is a class used to fine-tune the behavior of Pdf rendering by any the following methods:

IronPdf.AspxToPdf.RenderThisPageAsPDF
IronPdf.HtmlToPdf.RenderUrlAsPdf
IronPdf.HtmlToPdf.RenderHtmlAsPdf

PdfPrintOptions covers almost every pdf setting we can imagine, including editable PDF forms, javascript, custom headers and footers with {mail-merge} fields, paper sizes including custom sizes, margins …the whole kitchen sink.

Examples with HtmlToPdf¶

To make coding easier - there are 2 ways you can do set the PdfPrintOptions:

Construct HtmlToPdf with a PdfPrintOptions parameter. E.g.

HtmlToPdf myPdfMaker = new  HtmlToPdf(PdfPrintOptions);

HtmlToPdf has a property called PrintOptions which is an instance of PdfPrintOptions. This allows for on the fly settings changes. E.g.

HtmlToPdf myPdfMaker = new IronPdf.HtmlToPdf();
myPdfMaker.PrintOptions.GrayScale = true;
myPdfMaker.RenderHtmlAsPdf("<p>hello world</p>").SaveAs("test.pdf");
myPdfMaker.PrintOptions.Zoom = 200;


myPdfMaker.RenderHtmlAsPdf(@“<p>hello world</p>“).SaveAs(“test2.pdf”);

Example with AspxToPdf¶

For AspxToPdf your PdfPrintOptions are added as a final additional argument in the RenderThisPageAsPDF function call.

IronPdf.PdfPrintOptions PrintOptions = new PrintOptions(){ Dpi = 300 };
IronPdf.AspxToPdf.RenderThisPageAsPDF(AspxToPdf.FileBehaviour.Attachment, “FileName.pdf”, PrintOptions);

PdfResource can automatically save a file for you, but it can also return an ByteArray (byte[]) as raw binary data or a System.IO.MemoryStream.

This is useful if you want to post-process you pdf, save to a database, or do something innovative we haven’t even thought of yet!

Examples¶

using IronPdf;

HtmlToPdf myPdfMaker = new IronPdf.HtmlToPdf();
PdfResource  myPdf = myPdfMaker.RenderHtmlAsPdf("<p>hello world</p>");

//Now you have 3 ways to use the PDF data stored in myPdf:

This software builds on the shoulders of giants.

Our code product does make use of some great open source projects - and we are truly sorry not be to as generous nor as intelligent as they are.

It has become blasé industry policy to not give credit where it is due. We appreciate your open source projects - and appreciate even more that you have allowed us to use them in such a way that does not stop the sale or sub licensing of commercial software,

We honestly invest to day it back. To donate to each of these projects - wither in feedback, code, cash or developer love. Where we cant pay it back - we will try and pay it forwards!

Microsoft

We’ll be honest - we didn’t always love Microsoft. But they deserve a special praise on 2 counts.

Visual Studio 2015 Community Edition

Quite possible the best piece of IDE software ever written. No more need for JetBrains - everything and enterprise develop needs (including GitHub team workflow is incorporated). now its Free!

Than your Microsoft - you are now officially cool!

Open Sourcing of the .Net Framework In October 2014 - Microsoft open sourced the .Net framework. This will (already has) had massive implications for the future of C# as a language - and the common dream that we could have 1 programing framework for any task, on any device on any CPU architecture.

http://blogs.msdn.com/b/dotnet/archive/2014/11/12/net-core-is-open-source.aspx

The Open-Souring of Roslyn

The open sourcing of Roslyn, the core MSIL compiler makes for exciting future - such that logic from languages such as PHP, Python, Javascript, Ruby, C++, C, C+ and Java may one day be interoperable.

We honestly believe .Net may succeed Java as the future of universal programming.

Special Thanks

Thanks should also go to Slava Kolobaev and his work on the Pechkin PDF Interop for C# Project.

We were inspired by his clean C# architecture - and although out library does not use conventional Interop - he deserves a big thanks for sharing his design under CC Attribution license.

We wish we were as good at API design as you are!

Adobe

And Finally - Thank you adobe for opening up the PDF standard. You have proven that openness in proprietary software is financially viable.
