To view these images, your browser needs to be shipped with WebP support - for instance Chrome or Chromium, or Firefox using the WebP extension. Some (but not all) images in the frontend will then be served through WebP.
The following steps can be taken on the frontend-demo to see the extension in action:
Note that the demo-site will be refreshed periodically, and all existing data will be reset. Configurations you make in this demo-environment will no longer exist after this reset.
