[SOLVED] How to convert PPTX to PDF on a Non-Windows machine

How to convert PPTX to PDF on a Non-Windows machine

I'm sure many have come across this question, but I couldn't find any solutions for non-windows machines.

I need to prepare a Python script that can run on Linux (multiple versions) as well as On Windows machines. The script should read a PPT file, and convert it into a PDF, then convert 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 and Aspose, but both of them are commercial and we need to pay. Python pptx doesn't support conversion. Win32 is not available in Linux.

I am at a dead end.

This is the code I used to achieve the above (both the first and second parts) using the 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)

Solution

Try this code to convert any pptx file to pdf

 import subprocess
 import os

 def convert_pptx_to_pdf(input_path, output_dir):
 if not os.path.exists(output_dir):
    os.makedirs(output_dir)

 # Construct the command to convert pptx to pdf
  command = [
    'libreoffice',
    '--headless',
    '--convert-to',
    'pdf',
    '--outdir',
    output_dir,
    input_path
]

# Execute the command
subprocess.run(command, check=True)
print(f'Converted {input_path} to PDF and saved in {output_dir}')

# Specify the path to the .pptx file and the output directory
pptx_path = 'presentation.pptx'
output_directory = 'Desktop'

# Convert the .pptx file to PDF
convert_pptx_to_pdf(pptx_path, output_directory)
