The Syncfusion® HTML to PDF converter is a .NET library used to convert HTML or web pages to PDF document in WPF application.

Steps to convert Html to PDF document in WPF

Step 1: Create a new WPF application project.

In project configuration window, name your project and select Create.

Step 2: Install the Syncfusion.HtmlToPdfConverter.WPF NuGet package as a reference to your WPF application NuGet.org.

NOTE

Starting with v16.2.0.x, if you reference Syncfusion® assemblies from trial setup or from the NuGet feed, you also have to add “Syncfusion.Licensing” assembly reference and include a license key in your projects. Please refer to this link to know about registering Syncfusion® license key in your application to use our components.

Step 3: Include the following namespaces in the MainWindow.xaml.cs file.

C#

using System;
using System.IO;
using System.Windows;
using Syncfusion.Pdf;
using Syncfusion.HtmlConverter;

Step 4: Add a new button in MainWindow.xaml to convert HTML to PDF document as follows.

C#

<Grid HorizontalAlignment="Left" Margin="0,0,0,-0.333" Width="793">
<Button Content="Convert Html to PDF" HorizontalAlignment="Left" Margin="318,210,0,0" VerticalAlignment="Top" Width="166" Click=" btnCreate_Click " Height="19"/>
<TextBlock HorizontalAlignment="Left" Margin="222,177,0,0" TextWrapping="Wrap" VerticalAlignment="Top" Height="17"/>
<TextBlock HorizontalAlignment="Left" Margin="291,175,0,0" TextWrapping="Wrap" Text="Click the button to convert Html to PDF." VerticalAlignment="Top"/>
</Grid>

Step 5: Add the following code in btnCreate_Click to convert HTML to PDF document using Convert method in HtmlToPdfConverter class. The HTML content will be scaled based on the given ViewPortSize property of BlinkConverterSettings class.

C#

//Initialize HTML to PDF converter.
HtmlToPdfConverter htmlConverter = new HtmlToPdfConverter();
BlinkConverterSettings blinkConverterSettings = new BlinkConverterSettings();
//Set Blink viewport size.
blinkConverterSettings.ViewPortSize = new System.Drawing.Size(1280, 0);
//Assign Blink converter settings to HTML converter.
htmlConverter.ConverterSettings = blinkConverterSettings;
//Convert URL to PDF document.
PdfDocument document = htmlConverter.Convert("https://www.syncfusion.com");
//Create file stream.
FileStream stream = new FileStream("HTML-to-PDF.pdf", FileMode.CreateNew);
//Save the document into stream.
document.Save(stream);
//If the position is not set to '0' then the PDF will be empty.
stream.Position = 0;
//Close the document.
document.Close();
stream.Dispose();

By executing the program, you will get the PDF document as follows.
