Thank you! You're right: modern formats like webp (maybe not modern any more, it's been 10 years since it's initial release!) and avif can greatly reduce loading times. This article has some great image-optimizations outlined. For CMS-based systems, it's often easier to use CDN's like Akamai or Cloudflare. A content-editor uploads a full-size JPG, and these services will return the most optimized format (maybe webp), based on the browser-capabilities.
