How to convert PPT slides into image files in WPF

Step1: Create a WPF application in Visual Studio 2010 and add references
i)Microsoft Office 11.0 Object Library
ii)Microsoft PowerPoint 11.0 Object Library .

Step2: Add the following code in the XAML file:

Window x:Class="WpfApplication1.MainWindow"
Title="PPT to Image conversion" Height="350" Width="525"

Button Width="200" Height="200" Content="Generate Images from PPT" Click="Button_Click"


Step3: Add the following code in your MainWindow.xaml.cs:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Data;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Imaging;
using System.Windows.Navigation;
using System.Windows.Shapes;
using Microsoft.Office.Core;
using Microsoft.Office.Interop.PowerPoint;

namespace WpfApplication1
/// Interaction logic for MainWindow.xaml

public partial class MainWindow : Window
public MainWindow()


private void Button_Click(object sender, RoutedEventArgs e)
string filepathToImage = @"path to image.png";
string filepathToPPT = @"path to presentation.ppt";
Microsoft.Office.Interop.PowerPoint.Application presentationApplication = new Microsoft.Office.Interop.PowerPoint.Application();
Presentation ppt = presentationApplication .Presentations.Open(filepathToPPT , MsoTriState.msoFalse, MsoTriState.msoFalse, MsoTriState.msoFalse);
ppt.Slides[1].Export(filepathToImage , "png", 1024, 768);

Step 4: Run the application and click the button to see the image generated in the location you specified in the "filepathToImage" variable.
You can do the same for batch conversion by modifying the code accordingly.
