No tracking. WHY HEIF? HEIF (High Efficiency Image Format) uses the same compression family as HEVC video. It can produce files 40-60% smaller than JPEG at similar visual quality. iPhones have used HEIF for new photos since 2017, but older photos, screenshots, and images saved from other apps may still be JPG and take more space than necessary.
