Quick fact about AVIF
Web-optimized AVIF balances quality and size — typically 50-100 KB per image at web resolutions. Perfect for Core Web Vitals, LCP, and CDN efficiency.
Why compress AVIF?
AVIF is already efficient, but web delivery needs even smaller files. Web-optimized AVIF balances visual quality (still great on screens) with file size (50-100 KB) — improving Core Web Vitals, Largest Contentful Paint (LCP), and reducing CDN bandwidth costs.
