Why convert NEF to HEIC?

Not all image formats age equally. NEF (2003) predates many of today's requirements, while HEIC directly addresses iPhone photos — efficient storage. Converting NEF RAW images to HEIC 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. The gap becomes more obvious the more NEF files you're managing at once.

JPEG compression introduces minor quality loss — set quality to 90%+ to minimize
RAW conversion may take longer — files are processed via WebAssembly in your browser
