VVC in HEIF

For storage of high resolution, high definition images, the HEIF standard allows the use of Versatile Video Coding (VVC or H.266) encoded media. The VVC standard aims to provide further improvements in compression, outperforming other codecs especially with highest definition content. Below examples demonstrate the use of VVC in HEIF, to store 8K and 4K images, compressing them with a high ratio, retaining the quality of the original lossless image to a very high degree.

VVC vs HEVC

VVC (H.266) provides further compression gains over HEVC (H.265) for still images stored in HEIF. The following example compares the two codecs on the same scene.

Low overhead Image File Format (SlimHEIF)

SlimHEIF is the latest advancement in file size compression in the HEIF domain. The low overhead amendment to the HEIF standard [ISO/IEC 23008-12] defines a new file level structure that enables removal of redundant metadata from the file. This results in files storing small and simple images, such as icons, thumbnails or emojis, to be significantly smaller in size than their original HEIF counterparts. Experimental results on the topic show that a reduction of 30% to 80% in file size is achievable with SlimHEIF, presenting it to be a de facto standard for its applications.

HEIF vs Animated GIF

HEIF is also a suitable solution for storing of GIF-like image sequences, providing great compression and quality over the legacy format.

HEIF vs JPEG

In general HEIF with image payload encoded with HEVC codec, provides great advancements over legacy formats like JPEG. The following examples demonstrate the gains of HEVC encoding in HEIF, compared to JPEG. The quality and compression benefit is apparent and significant.
