Python 3.13.0rc1 : Simple convert all webp files from folder.

Today, a simple script is used to convert WEBP to PNG files from a defined folder.

The script reads a folder path for each WEBP file that is opened and saved as a PNG file.

import os
import sys
from PIL import Image

def convert_webp_to_png(directory):
    for root, dirs, files in os.walk(directory):
        for file in files:
            if file.endswith(".webp"):
                webp_path = os.path.join(root, file)
                png_path = os.path.splitext(webp_path)[0] + ".png"
                with Image.open(webp_path) as img:
                    img.save(png_path, "PNG")
                print(f"webp to png file: {webp_path} -> {png_path}")

if __name__ == "__main__":
    if len(sys.argv) != 2:
        print("How to use: python convert.py path_to_folder_with_webp_files")
        sys.exit(1)

    directory = sys.argv[1]
    if not os.path.isdir(directory):
        print(f"{directory} folder is not valid.")
        sys.exit(1)

    convert_webp_to_png(directory)
    print("Finished !")
