Example: Converting PDF to DOC 

// Specify the input and output file paths.
var inputPath = Path.Combine(@"C:\Samples\", "sample.pdf");
var outputPath = Path.Combine(@"C:\Samples\", "sample.docx");

// Create an instance of the PdfDoc plugin.
var plugin = new PdfDoc();

// Create an instance of the PdfToDocOptions class.
var options = new PdfToDocOptions
{
    SaveFormat = SaveFormat.DocX
};

// Add the input and output file paths to the options.
options.AddInput(new FileDataSource(inputPath));
options.AddOutput(new FileDataSource(outputPath));

// Process the PDF to Word conversion using the plugin and options.
var resultContainer = plugin.Process(options);

// Get the result from the result container.
var result = resultContainer.ResultCollection[0];

// Print the result.
Console.WriteLine(result);

Tips and Best Practices

  • Always initialize and validate your metered license before invoking the converter
  • For large PDFs, use page-range or batch conversion to optimize memory usage
  • Ensure custom fonts are available on the system or embedded in the PDF
  • Balance image compression and DPI for desired quality and file size
  • Dispose of converter instances promptly (use using blocks)
  • Reuse configuration objects but create fresh streams per operation in high-throughput scenarios
  • Use progress callbacks to update UI or implement cancellation logic
  • Monitor system resources during large-scale or parallel processing
