    for filename in os.listdir(input_dir):
        if filename.lower().endswith('.jpg') or filename.lower().endswith('.jpeg'):
            input_path = os.path.join(input_dir, filename)
            output_path = os.path.join(output_dir, filename)

            print(output_path)

            command = ['mozjpeg', '-quality', f'{quality}', '-outfile', output_path, input_path]
            subprocess.run(command, check=True)

if __name__ == "__main__":
    input_directory = r'C:\Users\xxx\Downloads\img\origin'  # 替换为你的输入目录路径
    output_directory = r'C:\Users\xxx\Downloads\img\press'  # 替换为你的输出目录路径
    compression_quality = 75  # 压缩质量(0-100)

    compress_images(input_directory, output_directory, compression_quality)
