How to Create New PowerPoint Presentation in Python

The following example accesses the first slide through a variable, adds a rectangle with addAutoShape, and saves the presentation as PPTX.

            
presentation = Presentation()
try:
    slide = presentation.getSlides().get_Item(0)
    slide.getShapes().addAutoShape(ShapeType.Rectangle, 50, 150, 300, 200)
    presentation.save("presentation.pptx", SaveFormat.Pptx)
finally:
    presentation.dispose()

How to Merge Presentations in Python

This example uses addClone to copy every slide from a source presentation to a destination presentation.

            
destination_presentation = Presentation("presentation1.pptx")
try:
    source_presentation = Presentation("presentation2.pptx")
    try:
        slide_count = source_presentation.getSlides().size()

        for slide_index in range(slide_count):
            slide = source_presentation.getSlides().get_Item(slide_index)
            destination_presentation.getSlides().addClone(slide)

        destination_presentation.save("combined-presentation.pptx", SaveFormat.Pptx)
    finally:
        source_presentation.dispose()
finally:
    destination_presentation.dispose()

How to Import a Presentation from PDF in Python

This example removes the default blank slide, calls addFromPdf, and saves the imported pages as a PPTX presentation.

            
presentation = Presentation()
try:
    presentation.getSlides().removeAt(0)
    presentation.getSlides().addFromPdf("document.pdf")
    presentation.save("presentation.pptx", SaveFormat.Pptx)
finally:
    presentation.dispose()

How to Convert PowerPoint to PDF in Python

This example calls save with SaveFormat.Pdf to convert a PowerPoint or OpenDocument presentation to PDF using the default options.

            
presentation = Presentation("presentation.pptx")
try:
    presentation.save("document.pdf", SaveFormat.Pdf)
finally:
    presentation.dispose()

How to Convert PowerPoint to JPG in Python

The following example calls getImage for each slide and saves the rendered images with ImageFormat.Jpeg.

            
presentation = Presentation("presentation.pptx")
try:
    slide_count = presentation.getSlides().size()

    for slide_index in range(slide_count):
        slide = presentation.getSlides().get_Item(slide_index)
        slide_image = slide.getImage(2, 2)
        try:
            file_path = f"slide-{slide_index + 1}.jpg"
            slide_image.save(file_path, ImageFormat.Jpeg)
        finally:
            slide_image.dispose()
finally:
    presentation.dispose()

FAQ

  • What has to be installed before `pip install aspose-slides-java` will work?
    A JRE 8 or later, Python 3.7 through 3.12, and JPype1 1.5.0 or later. The library talks to a Java runtime through JPype, so the JRE is a hard requirement.
  • How is this different from Aspose.Slides for Python via .NET?
    Same capabilities, different bridge. This build calls into Java and needs a JRE; the Python via .NET build carries its own runtime and needs nothing else installed. Choose this one if a JVM is already part of your environment.
  • Why do the methods look like `getSlides()` and `get_Item(0)`?
    Because the API is the Java one surfaced through JPype, so it keeps Java naming. Code written against the Python via .NET build will not run here unchanged.
  • Do I need to release the presentation explicitly?
    Yes. Call presentation.dispose() in a finally block, as the sample on this page does — the underlying Java object is not freed by Python’s garbage collector on its own.
