Why Convert PNG to AVIF?
AVIF (AV1 Image File Format) is a modern image format developed by the Alliance for Open Media. It offers significantly better compression than PNG, WebP and even JPEG — often 50% smaller at the same visual quality. It's ideal for web images where bandwidth and load time matter.
