[Fix] WebP Images do not have Thumbnails in File Explorer

WebP is a modern image format developed by Google that provides superior lossy and lossless compression for web images. When you open a folder containing WebP images, you may notice that none of them have thumbnails.

This issue may occur even if you have installed the WebP Image Extension from the Microsoft Store.

This post explains how to enable thumbnail previews for WebP images in File Explorer.

Resolution

Installing the Google WebP Codec should enable thumbnail support for WebP images in File Explorer. Here’s the direct download link for the same:
