HEIC vs GIF:
Name HEIC GIF
Full name High Efficiency Image File Format CompuServe Graphics Interchange Format
File extension .heic .gif
MIME image/heic image/gif
Developed by Moving Picture Experts Group (MPEG) CompuServe
Type of format Image Container Format Lossless bitmap image format
Introduction As HEIC is a container format, it can contain still images and image sequences (where a file contains more than one single image) that are coded in different formats. Currently, these include HEVC and H.264/MPEG-4 AVC (and JPEG for thumbnail/secondary images), though other coding formats may be added in the future. The main filename extension is .heic (for HEVC codec). 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 In Apple's implementation, for single images they have chosen the latter .heic filename extension (.heics for image sequence files) as the only one they will produce for photos, which indicates clearly that it went through HEVC encoding. 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.
