Resize Images in bulk and maintain aspect ratio with python | python project for beginners

[EduardoNicoleit]

from PIL import Image
import os

def resize(im, new_width):
width, height = im.size
ratio = height/width
new_height = int(ratio*new_width)
resized_image = im.resize((new_width, new_height))
return resized_image

files = os.listdir("assets")
extensions = ['jpg', 'png', 'jpeg']
for file in files:
ext = file.split('.')[-1]
if ext in extensions:
im = Image.open('assets/'+file)
im_resized = resize(im, 600)
new_dir = 'resized_images'
if not os.path.exists(new_dir):
os.makedirs(new_dir)
file = f'{new_dir}/{file}.jpg'
im_resized.save(file, 'png', quality=100)





Here you add the photos inside another folder called "assets" then it creates another folder with the resized images. Thanks for the video!

What's about fix height? Is new_width = int(ratio*new_height) ?
