| Introduction | High Efficiency Image File Format (HEIF) is a file format for individual images and image sequences. It was developed by the Moving Picture Experts Group (MPEG) and is defined by MPEG-H Part 12. In June 2017, Apple announced support for HEIF in macOS High Sierra and iOS 11. | The DirectDraw Surface container file format (uses the filename extension DDS), is a Microsoft format for storing data compressed with the proprietary S3 Texture Compression (S3TC) algorithm, which can be decompressed in hardware by GPUs. |
| Technical details | The HEIF specification also defines the means of storing High Efficiency Video Codec (HEVC)-encoded intra images and HEVC-encoded image sequences in which inter prediction is applied in a constrained manner. | The DirectDraw Surface format is useful for storing graphical textures and cubic environment maps as a data file, both compressed and uncompressed. The Microsoft Windows file extension for this data format is '.dds'. |
