I’m sure many have came across this question but I couldn’t find any solution for non-windows machines.

I need to prepare a python script that can run in linux (multiple versions) as well as in Windows machines. The script should read a PPT file and convert them into an PDF then I am converting the PDF into images. I can achieve the second part (PDF to images) but I can’t achieve the first part (PPT to PDF).

Can anyone please help me to achieve this?

I tried spire, Aspose but both are them are commercial and we need to pay. python pptx doesn’t support conversion. Win32 is not available in Linux.

I am at a deadend.
This is the code I used to achieve the above (both first and second part) using spire library but it doesn’t convert more than 10 pages.

!pip install Spire.Presentation

# Function to convert PPT to Images
def ppt_to_images(ppt_file, destination_folder):
    presentation = Presentation()
    presentation.LoadFromFile(ppt_file)
    presentation_name = ppt_file.split('/')[-1].split('.')[0]
    #Save PPT document to images
    for i, slide in enumerate(presentation.Slides):
        file_name = presentation_name + '_' + str(i) + ".png"
        image = slide.SaveAsImage()
        image.Save(destination_folder + '/' + file_name)
        image.Dispose()
    presentation.Dispose()
    return None

ppt_to_images("/content/drive/MyDrive/Colab Notebooks/DummyPPTs/dummy_powerpoint.pptx", OUTPUT_FOLDER)

Calling the above function using

ppt_to_images("/content/drive/MyDrive/Colab Notebooks/DummyPPTs/dummy_powerpoint.pptx", OUTPUT_FOLDER)
