In order to open a WebP format file in Photoshop you’ll need to install WebP plugin. To open, edit, and save WebP photos in Adobe Photoshop, you can simply download from the sources below (these are safe sources provided by Google):
Download the WebP Binary Format for Photoshop
from here: https://github.com/webmproject/WebPShop/releases.
Direct Link for WebP Photoshop in Windows
Direct Link for WebP Photoshop for MacOS
(extract the ZIP archive):
Move the plug-in (the .8bi binary for Windows or the .plugin folder for MacOS) to the Photoshop plug-in directory (
C:\Program Files\Adobe\Adobe Photoshop 2021\Plug-ins\ for Windows,
Applications/Adobe Photoshop/Plug-ins/ for Mac). Run Photoshop.
On macOS 10.15+, the prompt “WebPShop.plugin cannot be opened because the developer cannot be verified” can be bypassed by running the following in Terminal (Finder > Applications > Utilities):
sudo xattr -r -d com.apple.quarantine /Applications/Adobe\ Photoshop\ 2021/Plug-ins/WebPShop.plugin
