from groupdocs.conversion.options.convert import PdfConvertOptions

def convert_document_to_another_format():
    # Instantiate Converter with the input document 
    with Converter("./business-plan.docx") as converter:
        # Instantiate convert options to define the output format
        pdf_convert_options = PdfConvertOptions()
        
        # Convert the input document to PDF
        converter.convert("./business-plan.pdf", pdf_convert_options)    

if __name__ == "__main__":

• PdfConvertOptions – Options for converting to PDF format.
• ImageConvertOptions – Options for converting to Image formats (e.g., PNG, JPEG).
• WordProcessingConvertOptions – Options for converting to Word Processing formats.
• SpreadsheetConvertOptions – Options for converting to Spreadsheet formats.
• PresentationConvertOptions – Options for converting to Presentation formats.
• WebConvertOptions – Options for converting to Web formats (e.g., HTML).
• EBookConvertOptions – Options for converting to EBook formats (e.g., EPUB, MOBI).

• CadConvertOptions – Options for converting to CAD formats (e.g., DWG).
• ThreeDConvertOptions – Options for converting to 3D formats.
• FinanceConvertOptions – Options for converting to Finance formats (e.g., XBRL).

You can specify which document pages you would like to convert, as shown in the following example:

from groupdocs.conversion import Converter
from groupdocs.conversion.options.convert import PdfConvertOptions

def convert_specific_document_pages():
    # Instantiate Converter with the input document 
    with Converter("./business-plan.docx") as converter:
        # Instantiate convert options to define the output format
        pdf_convert_options = PdfConvertOptions()
        # Specify which document pages to convert
        pdf_convert_options.pages = [1, 3, 5]

        # Convert the specified pages of the input document to PDF
        converter.convert("./pages-1-3-5.pdf", pdf_convert_options)    

if __name__ == "__main__":
    convert_specific_document_pages()

As an alternative, you can specify a number of consecutive pages to convert, as shown in the following example:

from groupdocs.conversion import Converter
from groupdocs.conversion.options.convert import PdfConvertOptions

def convert_consecutive_document_pages():
    # Instantiate Converter with the input document 
    with Converter("./business-plan.docx") as converter:
        # Instantiate convert options to define the output format
        pdf_convert_options = PdfConvertOptions()
        # Specify the starting page and number of pages to convert
        pdf_convert_options.page_number = 1
        pdf_convert_options.pages_count = 5

        # Convert the specified range of pages in the document to PDF
        converter.convert("./pages-1-through-5.pdf", pdf_convert_options)    

if __name__ == "__main__":
    convert_consecutive_document_pages()
