LehmannLabs WebP Optimizer is focused on one core goal: faster page load times.
The plugin converts your WordPress images to WebP and serves WebP files on the frontend whenever available. This reduces image payload and helps improve Core Web Vitals and user experience.
It was developed for WordPress websites built with Elementor and works well with typical Elementor image output (including image widgets, carousels, and background image use cases).
Unlike many plugins in this category, LehmannLabs WebP Optimizer is fully free to use, with no advertising, no tracking, and no premium upsells. Many competing plugins are either limited in their free version or are generally only available as paid products.
