Why convert WEBP to AVIF?
Introduced in 2010 by Google, WEBP was great for its time. But AVIF (created in 2019 by Alliance for Open Media) offers lossy/lossless compression and 12-bit HDR – a massive leap forward. Modern web formats like AVIF offer superior compression compared to WEBP. Switching to AVIF can improve your Core Web Vitals and reduce bandwidth costs by 30–50%.
