Why convert NEF to AVIF?

Have you ever tried using a NEF image on a platform that doesn't support it? That's frustrating. By converting to AVIF, you get a universally compatible lossy/lossless file that works everywhere. 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.
