The Syncfusion .NET PowerPoint Library (presentation) offers powerful APIs for programmatically converting PowerPoint files to PDF with minimal code in C#, without Microsoft PowerPoint or interop dependencies. Additionally, it facilitates converting PowerPoints to PDF/A format for archival and tagged PDFs compliant with Section 508 (PDF/UA).
This example code shows how to convert a PowerPoint to PDF format using the Syncfusion .NET PowerPoint Library with just a few lines of code in C#.
using Syncfusion.Pdf;
using Syncfusion.Presentation;
using Syncfusion.PresentationRenderer;
//Open the PowerPoint file stream
using (FileStream fileStream = new FileStream("Template.pptx", FileMode.Open))
{
//Load an existing PowerPoint Presentation
using (IPresentation pptxDoc = Presentation.Open(fileStream))
{
//Convert PowerPoint into PDF document
using (PdfDocument pdfDocument = PresentationToPdfConverter.Convert(pptxDoc))
{
//Save the PDF file to file system
using (FileStream outputStream = new FileStream("PPTXToPDF.pdf", FileMode.Create, FileAccess.ReadWrite, FileShare.ReadWrite))
{
pdfDocument.Save(outputStream);
}
}
}
