How to Install IronPDF

Installing IronPDF is a straightforward process when using the NuGet Package Manager. To get started, open your .NET project in Visual Studio and navigate to the Solution Explorer. From there, right-click on your project and select "Manage NuGet Packages."

In the NuGet Package Manager window, switch to the Browse tab and search for "IronPDF." Once you've located the package, select it and click the "Install" button to begin the installation process. The package manager will guide you through the installation process with a series of prompts, including accepting the license agreement.

After completing the installation process, IronPDF will be added to your project, and you can start using it to generate PDF documents from your .NET application.

Convert an HTML String to a PDF

One of the core features of IronPDF is the ability to convert HTML strings to PDF documents. This can be done using the ChromePdfRenderer class, as shown in the code snippet below. It will create a PDF page containing the text.

using IronPdf;

// Instantiate Renderer
var renderer = new ChromePdfRenderer();

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

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

using IronPdf;

// Instantiate Renderer
var renderer = new ChromePdfRenderer();

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

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

Imports IronPdf

' Instantiate Renderer
Private renderer = New ChromePdfRenderer()

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

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

Convert a URL to a PDF

IronPDF also allows you to create a PDF from a URL, making it easy to convert webpages to PDFs.

using IronPdf;

// Instantiate Renderer
var renderer = new ChromePdfRenderer();

// Create a PDF from a URL or local file path
var pdf = renderer.RenderUrlAsPdf("https://ironpdf.com/");

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

using IronPdf;

// Instantiate Renderer
var renderer = new ChromePdfRenderer();

// Create a PDF from a URL or local file path
var pdf = renderer.RenderUrlAsPdf("https://ironpdf.com/");

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

Imports IronPdf

' Instantiate Renderer
Private renderer = New ChromePdfRenderer()

' Create a PDF from a URL or local file path
Private pdf = renderer.RenderUrlAsPdf("https://ironpdf.com/")

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

Convert an HTML Page to a PDF

Converting existing HTML files to PDFs is straightforward with IronPDF. Just use the RenderHtmlFileAsPdf method to create a PDF document from an HTML document.

using IronPdf;

// Instantiate Renderer
var renderer = new ChromePdfRenderer();

// Create a PDF from an existing HTML file using C#
var pdf = renderer.RenderHtmlFileAsPdf("example.html");

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

using IronPdf;

// Instantiate Renderer
var renderer = new ChromePdfRenderer();

// Create a PDF from an existing HTML file using C#
var pdf = renderer.RenderHtmlFileAsPdf("example.html");

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

Imports IronPdf

' Instantiate Renderer
Private renderer = New ChromePdfRenderer()

' Create a PDF from an existing HTML file using C#
Private pdf = renderer.RenderHtmlFileAsPdf("example.html")

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