How can I resize image with quality without saving image in Python?

Question

I use this code but it need to save

from PIL import Image
import requests
from io import BytesIO

response = requests.get(url)
img = Image.open(BytesIO(response.content))
image = img.resize((W, H), Image.ANTIALIAS)
image.save('De7k.jpeg', optimize=True, quality=Quality)

Answer 1

If you would like to "save" the file while keeping it in memory instead of writing a file to disk, you can write it to another BytesIO object.

from PIL import Image
import requests
from io import BytesIO

response = requests.get(url)
img = Image.open(BytesIO(response.content))
image = img.resize((W, H), Image.ANTIALIAS)
output = BytesIO()
image.save(output, format="JPEG", optimize=True, quality=Quality)
