Convert PowerPoint to PDF in C#

Nutrient .NET SDK (formerly GdPicture.NET) offers Office-to-PDF conversion that relies entirely on its own technology. The conversion doesn’t rely on third-party tools such as LibreOffice.

This article explains how to convert PowerPoint files such as PPT or PPTX to PDF.

Creating a PDF from a PowerPoint file

To create a PDF from a PowerPoint file, follow the steps below:

1. Create a GdPictureDocumentConverter object.
2. Load the source document by passing its path to the LoadFromFile method. Recommended: Specify the source document format with a member of the DocumentFormat enumeration.
3. Save the output in a new PDF document with the SaveAsPDF method.

The example below creates a PDF document from a PowerPoint file:

using GdPictureDocumentConverter gdpictureDocumentConverter = new GdPictureDocumentConverter();
// Load the source document.
gdpictureDocumentConverter.LoadFromFile(@"C:\temp\source.pptx", GdPicture14.DocumentFormat.DocumentFormatPPTX);
// Save the output in a new PDF document.
gdpictureDocumentConverter.SaveAsPDF(@"C:\temp\output.pdf");

Using gdpictureDocumentConverter As GdPictureDocumentConverter = New GdPictureDocumentConverter()
    ' Load the source document.
    gdpictureDocumentConverter.LoadFromFile("C:\temp\source.pptx", GdPicture14.DocumentFormat.DocumentFormatPPTX)
    ' Save the output in a new PDF document.
    gdpictureDocumentConverter.SaveAsPDF("C:\temp\output.pdf")
End Using
