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 Windows Forms.

Steps to convert PowerPoint to PDF programmatically

Step 1: Create a new C# Windows Forms application project.

Step 2: Install the Syncfusion.PresentationToPdfConverter.WinForms 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: Include the following namespaces in the Form1.cs file.

C#

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

Step 4: Add a new button in Form1.Designer.cs file.

C#

private Button btnCreate;
private Label label;
private void InitializeComponent()
{
    this.label = new System.Windows.Forms.Label();
    this.btnCreate = new System.Windows.Forms.Button();
    this.SuspendLayout();
    // 
    // label
    // 
    this.label.Location = new System.Drawing.Point(0, 40);
    this.label.Name = "label";
    this.label.Size = new System.Drawing.Size(426, 35);
    this.label.TabIndex = 0;
    this.label.Text = "Click the button to convert PowerPoint to PDF";
    this.label.TextAlign = System.Drawing.ContentAlignment.MiddleCenter;
    // 
    // btnCreate
    // 
    this.btnCreate.Location = new System.Drawing.Point(180, 110);
    this.btnCreate.Name = "btnCreate";
    this.btnCreate.Size = new System.Drawing.Size(85, 36);
    this.btnCreate.TabIndex = 1;
    this.btnCreate.Text = "Convert PPTX to PDF";
    this.btnCreate.Click += new System.EventHandler(this.btnConvert_Click);
}

Step 5: Add the following code in btnConvert_Click to convert a PowerPoint to PDF in Windows Forms.

C#

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