Compare Nikon Raw Image and Graphics Interchange Format formats — understand the key differences and when to use each
Nikon Raw Image
Nikon Raw Image (.nef) is a image file format.
Graphics Interchange Format
GIF (Graphics Interchange Format) was created by CompuServe in 1987 and remains one of the most recognizable image formats on the internet. GIF is best known for supporting animation — multiple frames played in sequence to create short looping clips. The format uses LZW lossless compression but is limited to a 256-color palette per frame, which makes it unsuitable for photographs but excellent for simple graphics, icons, and animated content. GIF supports 1-bit transparency (fully transparent or fully opaque, no semi-transparency). Animated GIFs are ubiquitous in messaging, social media, and web culture. However, GIF animations are often large in file size compared to modern alternatives like WebP or MP4. For static images, PNG provides better quality and compression. GIF remains popular due to its universal browser support and cultural significance.
