          input_folder = "pdf_files"
          output_folder = "word_files"
          
          for filename in os.listdir(input_folder):
            if filename.endswith(".pdf"):
              cv = Converter(os.path.join(input_folder, filename))
              cv.convert(os.path.join(output_folder, filename.replace(".pdf", ".docx")))
              cv.close()

3. Zamzar (for smaller batches)

Web service that processes files in the cloud (limited to 50 files at a time for free users).

Pros:

  • No software installation
  • Accessible from anywhere
  • Server-grade processing power

Cons:

  • Upload/download time for large batches
  • Privacy concerns for sensitive documents
  • Often have file size limits
Important Considerations for Large Batches:
  • File organization: Keep original PDFs and converted Word files in separate, well-labeled folders
  • Naming conventions: Ensure consistent naming to match source and output files
  • System resources: Large conversions may require significant RAM and CPU power
  • Error handling: Choose tools that provide conversion reports and error logs
  • Backup: Always keep original PDFs until you've verified the Word conversions

Optimization Tips for 100+ PDF Conversions

  1. Pre-sort your files: Group by similar layouts or content types for more consistent results
  2. Use batch processing: Process in chunks of 20-30 files rather than all 100 at once
  3. Check sample outputs: Convert a few test files first to adjust settings
  4. Consider OCR: For scanned PDFs, ensure your tool has OCR capabilities
  5. Automate naming: Use tools that support automatic output naming conventions

Conclusion

For converting 100+ PDFs to Word documents, Happy Convert or Adobe Acrobat Pro provide the most reliable solutions with excellent batch handling capabilities. Technical users might prefer command-line tools for automation, while cloud solutions work well for teams needing remote access. Remember that conversion quality can vary significantly based on the original PDF's complexity, so always test with representative samples before processing your entire batch.
