Thank you @preetpal for your response.

Understood your answer! Now, how do content delivery networks (CDNs) play a role in implementing AVIF or JPEG XL for global image delivery, and what considerations should businesses keep in mind when working with CDNs for image optimization?

CDNs are essential for delivering images globally, improving user experience overall and loading times. Because they preserve support for earlier formats while automatically converting picture formats to serve AVIF and JPEG XL to supported browsers. Moreover, content delivery networks (CDNs) store content at edge servers, lightening the burden on origin servers.

According to me, businesses need to think about file format support and browser compatibility when using CDNs for image optimization. As we know, optimizing picture transformation, compression, and financial concerns is crucial and to track picture performance, use tools for monitoring and reporting.
]For effective global content distribution, select a content delivery network (CDN) with a global reach then, make security a top priority to prevent unwanted access to photographs. Lastly, to guarantee seamless image distribution, extensive testing is essential prior to complete implementation. Do not forget to develop a fallback plan as well, providing a smooth user experience, for users using unsupported browsers.
