Implementation Guide

Convert PPT to PDF Feature

The primary functionality of GroupDocs.Conversion is its ability to transform PPT files into PDFs. Let’s break down the process:

Step 1: Load Your Presentation File

Create a new instance of the Converter class by providing it with the path to your PPT file.

Step 2: Set Conversion Options

Use PdfConvertOptions to specify any particular settings for the conversion, like starting page or password protection if needed.

var options = new PdfConvertOptions();
// Customize options as necessary

Step 3: Execute Conversion

Invoke the Convert method on your Converter instance, passing in the desired output path and conversion options. This step handles all processing and saves your PDF file.

Troubleshooting Tips

  • Common Issue: File not found error.
    • Solution: Verify that paths are correctly set and accessible.
  • Error During Conversion:
    • Check: Ensure input PPT files are not corrupted.
