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 ASP.NET MVC.

Steps to convert PowerPoint to PDF programmatically

Step 1: Create a new C# ASP.NET MVC application project.

Step 2: Select the MVC template to create the project.

Step 3: Install the Syncfusion.PresentationToPdfConverter.AspNet.Mvc5 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 4: Include the following namespace in that HomeController.cs file.

C#

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

Step 5: A default action method named Index will be present in HomeController.cs. Right click on this action method and select Go To View where you will be directed to its associated view page Index.cshtml.

Step 6: Add a new button in the Index.cshtml as shown below.

HTML

@{
    Html.BeginForm("ConvertPPTXtoPDF", "Home", FormMethod.Get);
    {
        <br />
        <div>
            <input type="submit" value="Convert PPTX to PDF" style="width:200px;height:27px" />
        </div>
    }
    Html.EndForm();
}

Step 7: Add a new action method ConvertPPTXtoPDF in HomeController.cs and include the below code snippet to convert a PowerPoint to PDF in ASP.NET MVC.

C#

//Open the file as Stream
using (FileStream pathStream = new FileStream(Server.MapPath("~/App_Data/Input.pptx"), FileMode.Open, FileAccess.Read))
{
    //Opens a PowerPoint Presentation
    using (IPresentation pptxDoc = Presentation.Open(pathStream))
    {     
        //Converts the PowerPoint Presentation into PDF document
        using (PdfDocument pdfDocument = PresentationToPdfConverter.Convert(pptxDoc))
        {
            //Saves the PDF document to MemoryStream.
            MemoryStream stream = new MemoryStream();
            pdfDocument.Save(stream);
            stream.Position = 0;
            //Download PDF document in the browser.
            return File(stream, "application/pdf", "Sample.pdf");
        }                    
    }
}
