Why convert NEF to AVIF?

People often ask why bother converting NEF at all. The short answer: AVIF handles Next-gen web images — superior compression noticeably better. Professional photographers often need to convert RAW files (like NEF) to web-friendly formats like AVIF. This reduces file size from 30 MB+ to under 500 KB while maintaining excellent quality – perfect for online portfolios and client galleries. It's a low-effort change with a disproportionately high payoff.
