I have written a small code to open webp image in the Anaconda prompt.
from PIL import Image
im = Image.open('test.webp')
It causes the following error:
C:\ProgramData\Anaconda3\lib\site-packages\PIL\Image.py:2655: UserWarning: image file could not be identified because WEBP support not installed
warnings.warn(message)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "C:\ProgramData\Anaconda3\lib\site-packages\PIL\Image.py", line 2657, in open
% (filename if filename else fp))
OSError: cannot identify image file 'test.webp'
The same code works fine in python-3.7.2-amd64 installed in another directory with Pillow 5.4.1.
Package Version
---------- -------
Pillow 5.4.1
pip 18.1
setuptools 40.6.2
The above code causes the same error in Anaconda prompt, Spyder and Jupyter Notebook. Still the same error even after reinstallation the Anaconda or trying on the different PC.
Anaconda or Miniconda version:
Anaconda 2018.12 for Windows Installer
Python 3.7 version 64-Bit Graphical Installer
Anaconda3-2018.12-Windows-x86_64.exe
Operating System:
Windows 10 Professional 64-Bit
The same issue was reported on GitHub #10737.

The question is whether Anaconda actually builds Pillow with webp support. Looking on the anaconda website I couldn't determine this. However, conda-forge does build Pillow with webp support, see here. So you might want to consider using that.
[...] libwebp provides the WebP format. Pillow has been tested with version 0.1.3, which does not read transparent WebP files. Versions 0.3.0 and above support transparency. I tried to fix this with the following command. It did not fix the issue for me. But it could be useful for others This installs version 1.0.1.
However, conda-forge does build Pillow with webp support, see here. So you might want to consider using that. I know, and that's the package that doesn't work on Windows. conda-forge is always my highest priority channel.
A plugin like WP Rocket loading the JS WebP scripts asynchronously. In that case, one can usually resolve it by adding “ewww_webp” to the exclusions in said plugin. If you’re not sure where to add the exclusion, you would need to consult with their support for assistance.
The pillow docs:
Many of Pillow’s features require external libraries:

This installs version 1.0.1.
Which results in no webp support
python

False
Same thing for conda install -c conda-forge libwebp.
It seems to still be an open issue for anaconda. That means perhaps the answer to your problem is to use pip instead of conda.

I downloaded all 5 of these.
conda install -c conda-forge libwebp
conda install -c conda-forge/label/gcc7 libwebp
conda install -c conda-forge/label/broken libwebp
conda install -c conda-forge/label/cf201901 libwebp
conda install -c conda-forge/label/cf202003 libwebp
Didn't get the error after this.
