HOW IT WORKS
When anyone access to a WordPress page, plugin check for images already converted to .webp. 
If one or more images have not been already converted, the plugin converts them immediately. 
Converted images are stored in a subfolder of wp-content folder: wp-content/wpmowebp

If WordPress go out of memory try to add 
define(‘WP_MEMORY_LIMIT’, ‘256M’); 
to your wp-config.php
