To convert and save a document by page, use the following methods of the Converter class:

• convert_by_page(output_path, convert_options): Converts each page of a document to the specified output format and saves them individually to disk.
• convert_by_page(file_path, page_number, convert_options): Converts a specific page of a document and saves it to the specified output file path.
• convert_by_page(stream, page_number, convert_options): Converts a specific page of a document and saves it to a provided stream.

The following ConvertOptions classes can be used with the convert_by_page method:

• 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).
• DiagramConvertOptions – Options for converting to Diagram formats (e.g., VSDX).
• PageDescriptionLanguageConvertOptions – Options for converting to Page Description Language formats (e.g., PostScript).
• 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).

The following example demonstrates how to convert each slide in a PPTX presentation to a PNG image and save the output images to a specified folder.

The file name template for the output files is converted-page-{page number}.{output file extension}. In this example, the first slide will be saved as converted-page-1.png.

from groupdocs.conversion import Converter
from groupdocs.conversion.filetypes import ImageFileType
from groupdocs.conversion.options.convert import ImageConvertOptions

def convert_all_document_pages():
    # Instantiate Converter with the input document 
    with Converter("./basic-presentation.pptx") as converter:
        # Instantiate convert options 
        png_convert_options = ImageConvertOptions()
        # Define the output format as PNG
        png_convert_options.format = ImageFileType.PNG
        
        # Convert all pages and save to the output folder
        converter.convert_by_page("./converted-pages", png_convert_options)    

if __name__ == "__main__":
    convert_all_document_pages()

The following example shows how to convert a specific slide in a PPTX presentation and save it as a separate file.

from groupdocs.conversion import Converter
from groupdocs.conversion.filetypes import ImageFileType
from groupdocs.conversion.options.convert import ImageConvertOptions

def convert_specific_document_page_to_file():
    # Instantiate Converter with the input document 
    with Converter("./basic-presentation.pptx") as converter:
        # Instantiate convert options 
        png_convert_options = ImageConvertOptions()
        # Define the output format as PNG
        png_convert_options.format = ImageFileType.PNG
        
        # Set the page number to convert and save it to a file
        page_number_to_convert = 3
        converter.convert_by_page("./slide-3.png", page_number_to_convert, png_convert_options)    

if __name__ == "__main__":
    convert_specific_document_page_to_file()

As an alternative, you can specify the stream to save the converted PNG image:

from groupdocs.conversion import Converter
from groupdocs.conversion.filetypes import ImageFileType
from groupdocs.conversion.options.convert import ImageConvertOptions

def convert_specific_document_page_to_file():
    # Instantiate Converter with the input document 
    with Converter("./basic-presentation.pptx") as converter:
        # Instantiate convert options 
        png_convert_options = ImageConvertOptions()
        # Define the output format as PNG
        png_convert_options.format = ImageFileType.PNG
        
        # Set the page number to convert and save it to a file
        page_number_to_convert = 5
        with open(f"./slide-{page_number_to_convert}.png", "w+b") as page_stream:
            converter.convert_by_page(page_stream, page_number_to_convert, png_convert_options)    

if __name__ == "__main__":
    convert_specific_document_page_to_file()
