WebP Express is a free WordPress plugin designed to enhance website performance by converting images to the WebP format, which is typically smaller in size compared to JPEG and PNG. By leveraging the WebP Convert library, it enables automatic image conversion using various local or cloud-based methods. The plugin seamlessly serves WebP images to compatible browsers while providing fallback options for those that do not support the format, ensuring a smooth user experience.

Key features include the ability to replace image tags with picture tags for better compatibility, and integration with caching solutions for improved load times. The plugin not only enhances website performance but also contributes to reduced bandwidth consumption, making it an eco-friendly choice. With a significant portion of web traffic now utilizing WebP-supporting browsers, WebP Express is a valuable tool for modern web development.
