Why Does iPhone Use HEIC?
Phone cameras generate huge libraries. HEIC typically shrinks file size versus JPG at similar perceived quality, which helps iCloud storage and on-device albums. Compatibility was the deliberate tradeoff.
Quick take: HEIC stores more detail in less space than JPG using HEIF/HEVC. Apple chose it for library efficiency — the cost is weaker support outside Apple devices.
Efficiency
HEVC-based stills inside HEIF often beat JPG on size for the same visual quality.
Apple ecosystem fit
Photos, Preview, AirDrop, and iCloud understand HEIC deeply.
The downside
Windows, many websites, and older Android apps still prefer JPG/PNG.
