How can I convert WEBP to PDF using Python?

Converting WEBP images to PDF using Python can be achieved using libraries such as Pillow (for image handling) and reportlab (for PDF creation). Here's a breakdown of the process:

1. Install Required Libraries:

- You'll need to install Pillow, reportlab and webp (if not installed already). You can do this using pip:

pip install pillow reportlab

pip install webp

Note that depending on your system, you may need to install the webp library through other means.

2. Write Python Code:

- Here’s a sample Python script to accomplish the conversion. This script will iterate through all files in a specified directory, and attempt to convert any that end with .webp into PDF files.

from PIL import Image
from reportlab.pdfgen import canvas
import os

def convert_webp_to_pdf(webp_path, pdf_path):
  try:
    image = Image.open(webp_path)
    if image.mode != 'RGB':
      image = image.convert('RGB')
    c = canvas.Canvas(pdf_path)
    width, height = image.size
    c.drawImage(image.filename, 0, 0, width, height)
    c.save()
    print(f"Converted: {webp_path} to {pdf_path}")
  except Exception as e:
    print(f"Error converting {webp_path}: {e}")

def convert_all_webp_in_directory(directory_path):
  for filename in os.listdir(directory_path):
    if filename.lower().endswith(".webp"):
      webp_file_path = os.path.join(directory_path, filename)
      pdf_file_name = os.path.splitext(filename)[0] + ".pdf"
      pdf_file_path = os.path.join(directory_path, pdf_file_name)
      convert_webp_to_pdf(webp_file_path, pdf_file_path)

if __name__ == "__main__":
  directory_path = "/path/to/your/webp/directory" #replace this with your directory
  convert_all_webp_in_directory(directory_path)

3. Explanation:

- The script first imports necessary modules Image, canvas, and os.

- The convert_webp_to_pdf function takes the path to a WEBP image and the desired output PDF path, opens the image using PIL, creates a PDF, and saves the image in it. If the image isn't in RGB, it converts to RGB format.

- The convert_all_webp_in_directory function takes a directory path and iterates through all the files, converting any webp files to pdf files in the same directory.

- In the main section, a directory_path variable must be replaced with the path to the directory where the webp files are, then it calls the function to convert all the files in the directory.

By following these steps, you should be able to convert WEBP images to PDF files using Python. Make sure to replace '/path/to/your/webp/directory' with the actual path to your WEBP files and consider adding more error handling.
