Why convert NEF to HEIF?

Want faster load times and lower bandwidth costs? Switch from NEF to HEIF. The difference is dramatic: lossless RAW vs lossy, 14-bit per channel vs 10-bit HDR. Converting NEF RAW images to HEIF applies essential post-processing: white balance, demosaicing, and tone mapping. The result is a standard image ready for printing or further editing in any software.

JPEG compression introduces minor quality loss — set quality to 90%+ to minimize
