IronPDF: A .NET PDF Library

IronPDF is a C# PDF library that can be used in .NET Core projects. It provides all the necessary APIs to manipulate PDF documents straightforwardly and intuitively. There are other PDF-generating libraries on the market, but this library has been designed as simply as possible to avoid confusion.

The main goal of this project is to provide a PDF library for .NET applications. It comes with many useful features, such as generating PDF files from HTML strings, converting PDFs to other formats, manipulating existing PDF documents, and generating PDF files directly from .NET Core projects. The IronPDF library also offers the ability to print PDF files with just a few lines of code. IronPDF can be used as a PDF converter. It can create multi-page spread tables using its accessible functions.

Let's begin using the IronPDF library in our project.

Create C# Project

The latest version of Visual Studio is recommended for creating this .NET project to ensure a smooth user experience. The IronPDF library is also compatible with a .NET Core project. The choice depends on the user, as the installation and use of IronPDF are identical across all .NET Frameworks. Follow the steps below to create a project in Visual Studio.

  • Start Visual Studio.
  • Click on "Create a new project".

The project will now be created. You can also use existing .NET Core projects with IronPDF. First, you need to install the library. The next section shows how to install the library.

Installation of the IronPDF Library

To install the IronPDF library from the command line, run the following command:

Install-Package IronPdf

You can get more information on the IronPDF website and the IronPDF NuGet page.

After installation, you will be able to use it in your .NET project. For more details about installation, visit the IronPDF installation guide.

Code Example

A web page for PDF files

using IronPdf;

var renderer = new ChromePdfRenderer();

// Choose Screen or Print CSS media
renderer.RenderingOptions.CssMediaType = Rendering.PdfCssMediaType.Screen;

// Set the width of the responsive virtual browser window in pixels
renderer.RenderingOptions.ViewPortWidth = 1280;

// Set the paper size of the output PDF
renderer.RenderingOptions.PaperSize = Rendering.PdfPaperSize.A2;

// Render the URL as PDF
var pdf = renderer.RenderUrlAsPdf("https://www.amazon.com/");

// Save the PDF to a local file
pdf.SaveAs("Amazon.pdf");
using IronPdf;

var renderer = new ChromePdfRenderer();

// Choose Screen or Print CSS media
renderer.RenderingOptions.CssMediaType = Rendering.PdfCssMediaType.Screen;

// Set the width of the responsive virtual browser window in pixels
renderer.RenderingOptions.ViewPortWidth = 1280;

// Set the paper size of the output PDF
renderer.RenderingOptions.PaperSize = Rendering.PdfPaperSize.A2;

// Render the URL as PDF
var pdf = renderer.RenderUrlAsPdf("https://www.amazon.com/");

// Save the PDF to a local file
pdf.SaveAs("Amazon.pdf");
Imports IronPdf

Private renderer = New ChromePdfRenderer()

' Choose Screen or Print CSS media
renderer.RenderingOptions.CssMediaType = Rendering.PdfCssMediaType.Screen

' Set the width of the responsive virtual browser window in pixels
renderer.RenderingOptions.ViewPortWidth = 1280

' Set the paper size of the output PDF
renderer.RenderingOptions.PaperSize = Rendering.PdfPaperSize.A2

' Render the URL as PDF
Dim pdf = renderer.RenderUrlAsPdf("https://www.amazon.com/")

' Save the PDF to a local file
pdf.SaveAs("Amazon.pdf")
$vbLabelText   $csharpLabel

This example shows how to convert a complex website UI to PDF, for example, the Amazon website, by following these steps:

  • Set the Media Type to Screen
  • Set the viewport width
  • Set the paper size of the output PDF. Page size is a significant factor in PDF files
  • Render the URL to PDF, using the Amazon URL as a source

Output

.NET Core PDF Library, Figure 5: Output PDF file rendered from Amazon website Output PDF file rendered from Amazon website

Simple PDF Creation

using IronPdf;

// Instantiate renderer
var renderer = new IronPdf.ChromePdfRenderer();

// Create a PDF from an HTML string using C#
using var pdf = renderer.RenderHtmlAsPdf("<h1>Hello World</h1>");

// Export to a file or Stream
pdf.SaveAs("output.pdf");

/****** Advanced Example with HTML Assets ******/
// Load external html assets: images, CSS, and JavaScript.
// An optional BasePath 'C:\\site\\assets\\' is set as the file location to load assets from
using var myAdvancedPdf = renderer.RenderHtmlAsPdf("<img src='icons/iron.png'>", @"C:\site\assets\");

// Save the PDF with assets to a file
myAdvancedPdf.SaveAs("html-with-assets.pdf");
using IronPdf;

// Instantiate renderer
var renderer = new IronPdf.ChromePdfRenderer();

// Create a PDF from an HTML string using C#
using var pdf = renderer.RenderHtmlAsPdf("<h1>Hello World</h1>");

// Export to a file or Stream
pdf.SaveAs("output.pdf");

/****** Advanced Example with HTML Assets ******/
// Load external html assets: images, CSS, and JavaScript.
// An optional BasePath 'C:\\site\\assets\\' is set as the file location to load assets from
using var myAdvancedPdf = renderer.RenderHtmlAsPdf("<img src='icons/iron.png'>", @"C:\site\assets\");

// Save the PDF with assets to a file
myAdvancedPdf.SaveAs("html-with-assets.pdf");
Imports IronPdf

' Instantiate renderer
Private renderer = New IronPdf.ChromePdfRenderer()

' Create a PDF from an HTML string using C#
Private pdf = renderer.RenderHtmlAsPdf("<h1>Hello World</h1>")

' Export to a file or Stream
pdf.SaveAs("output.pdf")

'''**** Advanced Example with HTML Assets *****
' Load external html assets: images, CSS, and JavaScript.
' An optional BasePath 'C:\\site\\assets\\' is set as the file location to load assets from
Dim myAdvancedPdf = renderer.RenderHtmlAsPdf("<img src='icons/iron.png'>", "C:\site\assets\")

' Save the PDF with assets to a file
myAdvancedPdf.SaveAs("html-with-assets.pdf")
$vbLabelText   $csharpLabel

The code above demonstrates how to use the HTML-to-PDF functionality of IronPDF. To use IronPDF, importing the namespace is necessary. Write using IronPdf; at the top of the program file to use it in the project.

The ChromePdfRenderer object is available for web support. The RenderHtmlAsPdf function can be used for converting HTML strings to PDF files. The function parameter accepts various types of sources, including an HTML string. You can also use images in your PDF document by setting the base path of images. After that, the SaveAs function is used to save the PDF file locally. You can choose simple HTML like the above and incorporate CSS, images, and JavaScript.

Headers & Footers

// Initialize the first page number
renderer.RenderingOptions.FirstPageNumber = 1; // use 2 if a cover page will be appended

// Set header options
renderer.RenderingOptions.TextHeader.DrawDividerLine = true;
renderer.RenderingOptions.TextHeader.CenterText = "{url}";
renderer.RenderingOptions.TextHeader.Font = IronPdf.Font.FontTypes.Helvetica;
renderer.RenderingOptions.TextHeader.FontSize = 12;
// Initialize the first page number
renderer.RenderingOptions.FirstPageNumber = 1; // use 2 if a cover page will be appended

// Set header options
renderer.RenderingOptions.TextHeader.DrawDividerLine = true;
renderer.RenderingOptions.TextHeader.CenterText = "{url}";
renderer.RenderingOptions.TextHeader.Font = IronPdf.Font.FontTypes.Helvetica;
renderer.RenderingOptions.TextHeader.FontSize = 12;
' Initialize the first page number
renderer.RenderingOptions.FirstPageNumber = 1 ' use 2 if a cover page will be appended

' Set header options
renderer.RenderingOptions.TextHeader.DrawDividerLine = True
renderer.RenderingOptions.TextHeader.CenterText = "{url}"
renderer.RenderingOptions.TextHeader.Font = IronPdf.Font.FontTypes.Helvetica
renderer.RenderingOptions.TextHeader.FontSize = 12
$vbLabelText   $csharpLabel

The above example demonstrates how to set headers and footers in the PDF file. IronPDF supports repeating headers in the document. IronPDF provides TextHeader and TextFooter properties to set various attributes of text, such as fonts, text position, etc. It can also convert HTML files to PDF files. Everything is straightforward with IronPDF. It can also merge PDF files efficiently, perform webpage-to-PDF conversions, enable automatic page numeration, and create digital signatures for PDFs using IronPDF. Furthermore, it produces PDF files of minimal file size with efficient compression.
