在Python中转换目录中的所有文件(.jpg到.png

import os
from PIL import Image

def convert_jpg_to_png(directory):
    for filename in os.listdir(directory):
        if filename.endswith(".jpg"):
            jpg_path = os.path.join(directory, filename)
            png_path = os.path.join(directory, filename.replace(".jpg", ".png"))
            try:
                img = Image.open(jpg_path)
                img.save(png_path, "PNG")
                print(f"Converted {jpg_path} to {png_path}")
            except Exception as e:
                print(f"Error converting {jpg_path}: {e}")

# 使用示例
directory_path = "path/to/your/directory"
convert_jpg_to_png(directory_path)
