Heavy quality reduction from RAW. GIF is for previews; use JPG/AVIF for final output.

Frequently Asked Questions

No, other than for a quick throwaway preview. GIF allows 256 colours per frame, and a 45 MP Nikon capture contains millions of distinct tones, so skies and skin collapse into visible bands. JPG, WEBP or AVIF all preserve the photograph.

Often not small at all. GIF compression is designed for flat areas of colour rather than photographic noise, so a converted Nikon frame frequently produces a file larger than the equivalent JPG while looking markedly worse. There is no file-size case for GIF here.

No. A NEF holds one exposure, so the output is a single static frame. Animation needs multiple source images, which a single Nikon RAW file cannot supply.

That is the 256-colour ceiling. A smooth gradient from a Nikon sensor contains thousands of subtle steps, and forcing them into 256 slots makes neighbouring tones merge into visible bands. Dithering scatters the error to disguise it, at the cost of a grainier picture.
