Ultimate Image Optimizer Extension for Magento 2 is the first extension that provides AVIF images support for Magento 2 stores.
Original images are converted to AVIF locally and automatically via Cron Job or command-line interface (CLI).
Besides AVIF images, the extension also creates WebP images and optionally also high-resolution/retina images automatically and allows to add lazy-load for the optimized images. The extension is 100% browser and full-page cache compatible. For browsers that do not support AVIF optimized images, WebP optimized images are used as fallback, for even older browsers, original images will be delivered to customers.
