如何使用python批量压缩图片_利用Python 批量压缩图片

方法一 直接调整宽高

先放参考资料：如何用Python智能批量压缩图片？

import math

from glob import glob

from PIL import Image

import os

def resize_images(source_dir, target_dir, threshold):

filenames = glob('{}/*'.format(source_dir))

if not os.path.exists(target_dir):

os.makedirs(target_dir)

for filename in filenames:

filesize = os.path.getsize(filename)

print(filename+":"+str(filesize))

if filesize >= threshold:

print(filename)

with Image.open(filename) as im:

width, height = im.size

new_width = int(threshold / filesize * width)

new_height = int(threshold / filesize * height)

resized_im = im.resize((new_width, new_height))

output_filename = filename.replace(source_dir, target_dir)

resized_im.save(output_filename)

source_dir = r"D:\图片"

target_dir = r"D:\压缩后的图片"

threshold = 200*1024 #限制在200k

resize_images(source_dir, target_dir, threshold)

方法二 通过tinify压缩

再放参考资料： 10 行 Python 代码，批量压缩图片 500 张，简直太强大了

import tinify

import os

tinify.key = '获取的key'

path = r"D:\图片" # 图片存放的路径

for dirpath, dirs, files in os.walk(path):

for file in files:

imgpath = os.path.join(dirpath, file)

print("compressing ..."+ imgpath)

tinify.from_file(imgpath).to_file(imgpath)
