I have managed to build Pillow 7.2.0 using pip like this:

pip install --upgrade Pillow==7.2.0 --global-option="build_ext" --global-option="--enable-webp"

Then in python console I've runned:

In [1]: from PIL import features
In [2]: print (features.check_module('webp'))
True

But my code:

response = requests.get(url)
img = Image.open(BytesIO(response.content))
with open(new_img, "bw+") as f:
    img.save(f, format="WEBP")

fails with:

~/src/myproject/.venv/lib/python3.8/site-packages/PIL/Image.py in save(self, fp, format, **params)
   2116             save_handler = SAVE_ALL[format.upper()]
   2117         else:
-> 2118             save_handler = SAVE[format.upper()]
   2119 
   KeyError: 'WEBP'

Is there anybody out there that has face this issue and can explain me how to fix it. Th anks in advance.

the workaround is to import the Image from WebPImagePlugin, and not directly from the PIL.

from PIL.WebPImagePlugin import Image

For docker users

I have added RUN apk add --update --no-cache libwebp-dev into my Dockerfile and it worked. Note that my Pillow version is Pillow==9.0.1
