Compare HEIF with GIF:
|Full name||High Efficiency Image File Format||CompuServe Graphics Interchange Format|
|Developed by||Moving Picture Experts Group (MPEG)||CompuServe|
|Type of format||Image Container Format||lossless bitmap image format|
|Introduction||High Efficiency Image File Format (HEIF) is a file format for individual images and image sequences. It was developed by the Moving Picture Experts Group (MPEG) and is defined by MPEG-H Part 12. In June 2017, Apple announced support for HEIF in macOS High Sierra and iOS 11.||The Graphics Interchange Format (better known by its acronym GIF) is a bitmap image format that was introduced by CompuServe in 1987 and has since come into widespread usage on the World Wide Web due to its wide support and portability.|
|Technical details||The HEIF specification also defines the means of storing High Efficiency Video Codec (HEVC)-encoded intra images and HEVC-encoded image sequences in which inter prediction is applied in a constrained manner.||GIF supports up to 8 bits per pixel for each image, allowing a single image to reference its own palette of up to 256 different colors chosen from the 24-bit RGB color space. GIF images are compressed using the Lempel-Ziv-Welch (LZW) lossless data compression technique to reduce the file size without degrading the visual quality.|
