HEIF (High Efficiency Image File Format) is the lossy image and animation format defined by MPEG-H Part 12 (ISO/IEC 23008-12).

It is closely related to the HEVC video format, so in that way it is similar to BPG. It uses boxes/atoms format as a container format, so in that way it is similar to JPEG 2000.

Format details

[This section contains educated guesses, and may be incorrect.]

The standard apparently defines:

  • A still image ("image collection") container format, based on boxes/atoms format, with brand mif1. It uses some elements from ISO-BMFF (though note that still image formats cannot be technically valid ISO-BMFF).
  • An animated image ("image sequence") container format, with brand msf1. This might qualify as valid ISO-BMFF.
  • An image compression scheme, with brand heic.
  • Various other compression schemes for use in the above containers, for example based on AVC or JPEG.

Some or all files that use heic compression should use file extension .heic. Other files may use .heif, or something else.

Identifiers

Based on source code and sample files, it usually uses the brands mif1 and heic. Some files may use other brands, such as msf1 and heix.
