High Efficiency Image File Format
open-in-new
<p>High Efficiency Image File Format (HEIF) is a digital <a href="/facts/Container_format/mSfwwdSA">container format</a> for storing individual <a href="/facts/Digital_image/3TNT47Mv">digital images</a> and image sequences. The standard covers <a href="/facts/Multimedia/PtJteq27">multimedia</a> files that can also include other media streams, such as <a href="/facts/Timed_text/j0QtVVga">timed text</a>, audio and video. </p><p>HEIF can store images encoded with multiple coding formats, for example both <a href="/facts/Standard-dynamic-range_video/URDwL3DT">SDR</a> and <a href="/facts/High-dynamic-range_video/jzRH1mFe">HDR</a> images. <a href="/facts/High_Efficiency_Video_Coding/6gp7DC1a">HEVC</a> is an 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 <a href="/facts/JPEG/HQ8QS3uB">JPEG</a>. </p><p>HEIF files are a special case of the <a href="/facts/International_Organization_for_Standardization/IacYR7Yg">ISO</a> Base Media File Format (<a href="/facts/ISO_base_media_file_format/whvAPejY">ISOBMFF</a>, ISO/IEC 14496-12), first defined in 2001 as a shared part of <a href="/facts/MP4/PM0FNvUU">MP4</a> and <a href="/facts/JPEG_2000/GAzXdHI2">JPEG 2000</a>. Introduced in 2015, it was developed by the <a href="/facts/Moving_Picture_Experts_Group/ygmT7JBB">Moving Picture Experts Group</a> (MPEG) and is defined as Part 12 within the <a href="/facts/MPEG-H/jQTqHyYy">MPEG-H</a> media suite (ISO/IEC 23008-12). </p>
