Syncfusion DocIO is a .NET Word library used to create, read, edit, and convert Word documents programmatically without Microsoft Word or interop dependencies. Using this library, you can convert a Word document to PDF in WPF.

Steps to convert Word document to PDF in WPF

Step 1: Create a new WPF application project.

Step 2: Install the Syncfusion.DocToPdfConverter.Wpf NuGet package as a reference to your WPF application from 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 Syncfusion.DocIO.DLS;
using Syncfusion.DocIO;
using Syncfusion.DocToPDFConverter;
using Syncfusion.Pdf;

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

C#

<Button Click="btnConvert_Click" Margin="0,0,10,12" VerticalAlignment="Bottom" Height="30" BorderBrush="LightBlue" HorizontalAlignment="Right" Width="180">
    <Button.Background>
        <LinearGradientBrush EndPoint="0.5,-0.04" StartPoint="0.5,1.04">
            <GradientStop Color="#FFD9E9F7" Offset="0"/>
            <GradientStop Color="#FFEFF8FF" Offset="1"/>
        </LinearGradientBrush>
    </Button.Background>
    <StackPanel Orientation="Horizontal" Height="23" Margin="0,0,0,-2.52" VerticalAlignment="Bottom" HorizontalAlignment="Right" Width="100">
        <Image Name="image2" Margin="2" HorizontalAlignment="Center" VerticalAlignment="Center" />
        <TextBlock Text="Convert Word to PDF" Height="15.96" Width="126" Margin="0,4,0,3" />
    </StackPanel>
</Button>

Step 5: Add the following code in btnConvert_Click to convert Word document to PDF with simple text.

C#

//Open an existing Word document.
using (WordDocument document = new WordDocument(Path.GetFullPath(@"../../Data/Input.docx"), FormatType.Docx))
{
    //Instantiation of DocToPDFConverter for Word to PDF conversion
    using (DocToPDFConverter converter = new DocToPDFConverter())
    {
        //Converts Word document into PDF document
        using (PdfDocument pdfDocument = converter.ConvertToPDF(document))
        {
            //Saves the PDF document
            pdfDocument.Save(Path.GetFullPath(@"../../Sample.pdf"));
        }
    };
}
