Description
A still image stored in a HEIF container with the pixels coded as AVC (H.264) instead of HEVC, under the 'avci' brand of the AVC Image File Format (ISO/IEC 23008-12). The container is the same one as .heic; only the codec inside differs.
Image file format related to the .PNG format, but uses lossy compression like standard .JPG files; developed as a sub-format for .MNG objects, but can also be used as a standalone raster image format.
