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

Steps to convert PowerPoint to PDF programmatically

Step 1: Create a new C# WPF application project.

Step 2: Install the Syncfusion.PresentationToPdfConverter.Wpf NuGet package as reference to your .NET Standard applications 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: Add a new button in the MainWindow.xaml as shown below.

C#

<Window x:Class="Create_PowerPoint_Presentation_to_PDF.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
        xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
        xmlns:local="clr-namespace:Create_PowerPoint_Presentation_to_PDF"
        mc:Ignorable="d"
        Title="MainWindow" Height="450" Width="800">
    <Grid>
        <Button Click="btnConvert_Click" VerticalAlignment="Center" Height="19" BorderBrush="LightBlue" HorizontalAlignment="Center" Width="120">
            <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="20" VerticalAlignment="Center" HorizontalAlignment="Left" Width="140">
                <Image Name="image2" Margin="2" HorizontalAlignment="Center" VerticalAlignment="Center" />
                <TextBlock Text="Convert PPTX to PDF" Height="16" Width="126" />
            </StackPanel>
        </Button>
    </Grid>
</Window>

Step 4: Include the following namespaces in the MainWindow.xaml.cs file.

C#

using Syncfusion.Presentation;
using Syncfusion.PresentationToPdfConverter;
using Syncfusion.Pdf;

Step 5: Add the following code in btnConvert_Click to convert PowerPoint to PDF in WPF.

C#

//Opens a PowerPoint Presentation.
using (IPresentation pptxDoc = Presentation.Open(Path.GetFullPath(@"../../Data/Input.pptx")))
{
    //Converts the PowerPoint Presentation into PDF document.
    using (PdfDocument pdfDocument = PresentationToPdfConverter.Convert(pptxDoc))
    {
        //Saves the PDF document.
        pdfDocument.Save(Path.GetFullPath(@"../../Sample.pdf"));
    }                   
}
