Convert PPSX Slides to PNG Images in Python

Convert PPSX to PNG in Python

Aspose.Slides for Python via Java can render the slides in a PowerPoint Slide Show (.ppsx) as PNG images without Microsoft PowerPoint. Because a PNG file stores one image, the conversion creates a separate output file for each slide. Animations, transitions, and other interactive behavior are not included in the images.

Use Presentation.getSlides to iterate through the source slides. For each Slide, call getImage and save the returned image with ImageFormat.Png. The scaling values passed to getImage control the output dimensions relative to the original slide size.

How to Convert PPSX to PNG in Python

Load the PPSX file into a Presentation, render each slide with getImage, and save each result in PNG format.

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

    for slide_index in range(slide_count):
        slide = presentation.getSlides().get_Item(slide_index)
        slide_image = slide.getImage(2.0, 2.0)
        try:
            slide_number = slide_index + 1
            file_path = f"slide-{slide_number}.png"
            slide_image.save(file_path, ImageFormat.Png)
        finally:
            slide_image.dispose()
finally:
    presentation.dispose()
