Why convert WebP to AVIF?
WebP cut your image weight by 25-35% over JPG. AVIF cuts it by another 20-30% over WebP. For sites chasing Lighthouse / Core Web Vitals or anyone paying for CDN bandwidth by the gigabyte, the migration is a real lever. Every modern browser renders AVIF natively, so for web assets the conversion is essentially free quality-for-bytes.
Don't convert when the asset has to leave the web — older email clients, Microsoft Office, plenty of corporate uploaders, and most third-party design tools still don't handle AVIF reliably. Keep WebP (or even JPG) as the fallback for those workflows.
