Why convert NEF to PNG?

The main issue with NEF is lack of browser support. Converting to PNG fixes this by providing perfect pixel preservation with smaller files. Professional photographers often need to convert RAW files (like NEF) to web-friendly formats like PNG. This reduces file size from 30 MB+ to under 500 KB while maintaining excellent quality – perfect for online portfolios and client galleries.
