利用Python 批量壓縮圖片

方法一 直接調整寬高

先放參考資料：如何用Python智能批量壓縮圖片？

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:\圖片"
target_dir = r"D:\壓縮後的圖片"
threshold = 200*1024 #限制在200k

resize_images(source_dir, target_dir, threshold)

方法二 通過tinify壓縮

再放參考資料： 10 行 Python 代碼，批量壓縮圖片 500 張，簡直太強大了

import tinify
import os

tinify.key = '獲取的key'
path = r"D:\圖片" # 圖片存放的路徑

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)
