Why convert DNG to AVIF?

Introduced in 2004 by Adobe, DNG 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. Professional photographers often need to convert RAW files (like DNG) 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.
