Description
Compressed bitmap image that uses wavelet compression instead of the DCT compression used by standard .JPEG images; supports 16-bit color, alpha transparency, and lossless compression.
Based on HEVC (High-Efficiency Video Coding), the HEIF format is an image file container with one or multiple images and is the default image format for Apple Live Photos. It replaced the JPEG format as it's smaller in size and has lossless compression ensuring high-quality photos.
