from PIL import Image  
import os  
  
# 定义原文件夹路径和目标文件夹路径  
source_folder = "path/to/source/folder"  
target_folder = "path/to/target/folder"  
  
# 遍历原文件夹中的所有图片文件  
for filename in os.listdir(source_folder):  
    if filename.endswith(".png"):  
        # 打开图片文件并转换格式  
        with Image.open(os.path.join(source_folder, filename)) as img:  
             img = img.convert('RGB')  
             img.save(os.path.join(target_folder, filename.replace('.png', '.jpg')))

.png转.jpg尺寸不变

将文件夹里的图片修改为指定尺寸

复制代码

from PIL import Image  
import os  
  
# 定义原文件夹路径和目标文件夹路径  
source_folder = "/home/uto/数据/img_dir"  
target_folder = "/home/uto/数据/image_6"  
  
# 遍历原文件夹中的所有图片文件  
for filename in os.listdir(source_folder):  
    if filename.endswith(".jpg") or filename.endswith(".jpeg") or filename.endswith(".png"):  
        # 打开图片文件并调整大小  
        with Image.open(os.path.join(source_folder, filename)) as img:  
             img = img.resize((1280, 720))  
             # 保存到目标文件夹中并保持原有文件名  
             img.save(os.path.join(target_folder, filename))
