Why convert NEF to WEBP?

Because NEF files use lossless RAW compression and 14-bit per channel, they are not ideal for Modern web images — best compression. Converting them to WEBP (lossy/lossless, 24-bit) solves this. Professional photographers often need to convert RAW files (like NEF) to web-friendly formats like WEBP. This reduces file size from 30 MB+ to under 500 KB while maintaining excellent quality – perfect for online portfolios and client galleries.
