Usage Notes

  • For large PDFs, use --pages to limit extraction scope
  • Table extraction works best with well-structured tables; complex layouts may need manual cleanup
  • PDF generation via WeasyPrint supports CSS styling — pass a --css file for custom styles
  • All paths can be absolute or relative to the workspace
