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.

– Elementor v3.35.6

<h4>🌐 Why WebP?</h4>
WebP is a modern image format developed by Google that delivers significantly smaller file sizes compared to JPEG and PNG — often by 25–50%, while maintaining high visual quality.
Using WebP helps you: 
* 🚀 Improve page load speed 
* 📉 Reduce bandwidth usage 
* 🔍 Boost SEO and Core Web Vitals 
* 📱 Enhance user experience on mobile devices
<h4>⚡ Bulk Optimization</h4>
Optimize all existing images in your media library with a single click.
⚠️ Important: Test your settings on a few images first. Bulk optimization is irreversible.
<h4>⚙️ Settings</h4>
Go to Settings → Web Pixel Studio Image Compressor in your WordPress dashboard. 
Here you can configure image quality, compression method, WebP conversion, and other optimization options.
