Convert images to PDF

You can use the Python package PyPDF2 to convert images to PDF in Python. Here’s an example code:

import os
from PIL import Image
from PyPDF2 import PdfFileMerger

# Set the directory containing the images
directory = './images/'

# Get a list of all the image file names in the directory
image_files = [filename for filename in os.listdir(directory) if filename.endswith('.jpg')]

# Sort the file names alphabetically
image_files.sort()

# Create a new PDF file
pdf_output = './output.pdf'
pdf_merger = PdfFileMerger()

# Loop through all the image files and convert each one to a PDF page
for image_file in image_files:
    # Open the image and convert it to grayscale
    image = Image.open(directory + image_file).convert('RGB')

    # Create a new PDF page and add the image to it
    pdf_page = Image.new('RGB', image.size, 'white')
    pdf_page.paste(image, mask=image.convert('RGBA'))

    # Add the PDF page to the PDF file
    pdf_merger.append(pdf_page)

# Save the PDF file
pdf_merger.write(pdf_output)
pdf_merger.close()

In this code, we use the Pillow library (a fork of the Python Imaging Library or PIL) to open the image files and convert them to grayscale. Then, we create a new PDF page and paste the image onto it. Finally, we use the PdfFileMerger class from the PyPDF2 library to merge all the PDF pages into a single PDF file. Note that in this example, we assume that all the images are in JPEG format and that they are located in a directory named “images” in the current working directory.
