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.
Tested with: 
– Elementor v3.35.6 
– Elementor Pro v3.35.1
Key benefits: 
– Faster frontend image delivery through WebP replacement 
– Completely free, with no ads and no paid upgrades 
– Optional auto-conversion on upload 
– Batch conversion for existing media 
– Safe fallback strategy and backup/restore tools 
– No external API calls, no tracking
Main features: 
– WebP generation for full-size and intermediate image sizes 
– Output modes: 
 – Picture mode (recommended): WebP source with fallback image 
 – Direct mode: direct URL/srcset replacement to WebP when available 
– Original image backup to <code>uploads/slimage-backup/YYYY/MM/</code>
