The core plugin functionality is optimizing the images in your library, you can either check a box and let us do all the work in the background, or you cand bulk select them.
All the api calls done are secured via a unique per image token.
The plugin also includes a lazy loading feature, it finds the images in your WordPress site and adds the loading=”lazy” tag.
