WebP Converter
Converts Image to WebP and AVIF format
Side-by-side comparison of the same photo. WebP is generated automatically with the _iwebp.webp suffix next to the original file.
Large photographic JPEGs see dramatic savings while staying visually sharp at the default quality setting.
When the plugin is enabled, every <img> on the page is served as WebP automatically. The markup below references a JPG — visitors receive the optimised WebP version.
The plugin also rewrites srcset attributes so retina and responsive image sets stay optimised.
