'''High Efficiency Image File Format''' ('''HEIF''') is a digital [[container format]] for storing individual [[digital image]]s and image sequences. The standard covers [[multimedia]] files that can also include other media streams, such as [[timed text]], audio and video.<ref name="JCTVC" />

HEIF can store images encoded with multiple coding formats, for example both [[Standard-dynamic-range video|SDR]] and [[High-dynamic-range video|HDR]] images. [[High Efficiency Video Coding|HEVC]] is ana [non-free](https://en.wikipedia.org/wiki/Royalty-free) image and video encoding format and the default image codec used with HEIF. HEIF files containing HEVC-encoded images are also known as '''HEIC''' files. Such files require less storage space than the equivalent quality [[JPEG]].<ref name="CNET" /><ref name="LesShu" />

HEIF files are a special case of the [[International Organization for Standardization|ISO]] Base Media File Format ([[ISO base media file format|ISOBMFF]], ISO/IEC 14496-12), first defined in 2001 as a shared part of [[MP4]] and [[JPEG 2000]]. Introduced in 2015, it was developed by the [[Moving Picture Experts Group]] (MPEG) and is defined as Part 12 within the [[MPEG-H]] media suite (ISO/IEC 23008-12).
