Hello @teeboy4real,
Thanks for your message.
The most important difference is that my plugin provides support for older browsers. By using only the WebP format, we do not support a certain group of older browsers. By using only the AVIF format, we do not support more than 30% of browsers. My plugin allows you to serve the best images depending on the browser of the user of your website.
When the browser tries to download an image file, the server checks if it supports the AVIF format (if enabled in the plugin settings). If so, the browser will receive an equivalent of the original image in AVIF format. If it does not support AVIF, but supports the WebP format, the browser will receive an equivalent of the original image in WebP format. If the browser does not support either WebP or AVIF, the original image is loaded. This means full support for all browsers.
Best,
Mateusz
