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.

Most optimization plugins slow down your site with external API calls or crash your server by processing huge files. Auto WebP Converter is different. It runs entirely on your server using the native PHP GD library, featuring a unique Smart Memory Guard that calculates available RAM before processing to prevent crashes.
