What is HEIC?

HEIC is a file extension for images saved in the High Efficiency Image File Format (HEIF), a modern container based on the ISO Base Media File Format. In Apple’s ecosystem, “HEIC” typically means HEIF images encoded with HEVC (H.265). Compared with JPEG, HEIC delivers similar or better visual quality at much smaller sizes, and supports advanced features: 10-bit color, wide-gamut profiles, transparency, multiple images per file (bursts, Live Photos), depth maps, and rich metadata. HEIC opens on iOS, macOS, and most modern Android devices; Windows 10/11 can add support via HEIF/HEVC extensions. For web or legacy tools, convert to JPG or PNG, or to AVIF when targeting maximum compression with broad browser support. HEIC is ideal for phone photography, archives, and efficient cloud storage.
