WebPQuickLook

The plugin extends macOS Quick Look to support Google’s WebP image format, enabling both preview and thumbnail generation for .webp files directly in Finder. When a user selects a WebP file and presses the space bar, the system displays the image as it would for any native format, and thumbnails appear in folder views without opening an external application.

It is intended for macOS users who work with WebP images and want seamless integration into the standard file‑browsing workflow. Installation can be performed via a provided shell script or through Homebrew’s cask system, with an additional script for system‑wide deployment that requires administrator credentials.

The solution operates entirely within the existing Quick Look framework, requiring no separate viewer or additional software after installation. It is marked as stable and targets the core macOS platform.
