# IMPORTANT: Install the webp Python package, using the following command:
# pip3 install --user webp
# Import the webp package
import webp
# Load a PIL image array from the specified .webp animation file
anim = webp.load_images('giphy.webp')
# Grab a reference to the first frame, and save the entire PIL image array as GIF with 70ms frames (14.286 FPS)
anim[0].save('output.gif', save_all=True, append_images=anim[0:], duration=70, loop=0)

I can reproduce in Docker. Module must be broken.

I noticed my python is the 32 bit version, and the webptools executables are 64 bit, maybe that's why I can't install neither webp or webptools modules. I'll try to test this hypothesis with a virtual machine so I don't mess up something

FeraruSilviuMarian commented Sep 13, 2021

The two methods (webp and PIL) yield the same poor image quality, the colors are fewer, the colors feel 8 bit or so

`import webp
from PIL import Image

im = Image.open(r'C:\Users\silve\Downloads\25036996.webp')
im.info.pop('background', None)
im.save(r'C:\Users\silve\Downloads\test.gif', 'gif', save_all=True)

anim = webp.load_images(r'C:\Users\silve\Downloads\25036996.webp')
anim[0].save(r'C:\Users\silve\Downloads\test2.gif', save_all=True, append_images=anim[0:], duration=70, loop=0)`
