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. The same conversion pipeline also supports OpenDocument Text (ODT) (.odt) and Rich Text Format (RTF) (.rtf) inputs. 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

During conversion, Nutrient preserves common document layout features, including tables inside text boxes and frames, text highlights in OpenDocument files, text wrapping around shapes, bidirectional text in DOCX files — such as Arabic or Hebrew text embedded in left-to-right paragraphs — and straight line connectors in Word and RTF files.

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.
