High Efficiency Image File Format (.heif)

The High Efficiency Image File Format (HEIF) represents a significant advancement in image file technology. Developed by the Moving Picture Experts Group (MPEG), HEIF is codified under MPEG-H Part 12 (ISO/IEC 23008-12) and is designed to optimize the compression and storage of images and sequences. This format is particularly beneficial for multimedia applications where file size without sacrificing quality is paramount. HEIF stands out for its ability to consolidate multiple images into a single file. This can include a series of photographs, a primary image alongside its thumbnail, or various perspectives of a scene necessary for stereo or multi-view photography.

As an advanced codec, HEIF incorporates features like sequence playback, burst shots, depth information, and dynamic pictures. It operates as a container that can encapsulate data in diverse formats, notably HEVC (High Efficiency Video Codec or H.265). By employing HEVC for compression, HEIF achieves far greater efficiency than traditional formats such as JPEG. Additionally, HEIF supports the retention of editing actions (e.g., crop, rotate) and metadata (e.g., time stamps, camera settings), enhancing its utility and adaptability for both professional and hobbyist photographers.
