Converting a document from DOCX to PDF format

Converting Word documents (DOCX) to PDF — whether for compliance, legal, or archival purposes — ensures critical content is preserved in a tamper-proof form that maintains its original appearance over time.

How Nutrient helps you achieve this

Nutrient Python SDK handles DOCX-to-PDF conversion. With the SDK, you don’t need to worry about:

  • Parsing Word document structures
  • Managing text and layout formatting
  • Handling fonts and styling
  • Complex rendering logic

Instead, Nutrient provides an API that handles all the complexity behind the scenes, letting you focus on your business logic.

Complete implementation

Below is a complete working example that demonstrates DOCX-to-PDF conversion. These lines set up the Python application. The import statements bring in all necessary classes from the Nutrient SDK:

from nutrient_sdk import Document
from nutrient_sdk import NutrientException

This line opens the Word document. The context manager(opens in a new tab) syntax ensures the document is automatically closed when you’re done, preventing resource leaks:

def main():
    try:
        with Document.open("input.docx") as document:

This block exports the document to PDF and saves it as output.pdf. The try-except block handles potential errors using NutrientException:

            document.export_as_pdf("output.pdf")
            print("Successfully converted to output.pdf")
    except NutrientException as e:
        print(f"Error: {e}")


if __name__ == "__main__":
    main()

Conclusion

The conversion logic consists of two steps:

  1. Open the document.
  2. Export as PDF.

Nutrient handles Word document parsing and PDF rendering so you don’t need to understand document internals or manage layout conversion manually.
