> HEIF isn't an Apple owned format […]
I'm also thinking the OP meant HEIC, but I know that it is not proprietary (though as noted patented), and wanted to make sure, as a lot of people of all sorts of assumptions/misconceptions about Apple.
HEIF/HEIC is based on H.265, so not Apple-only as Android supports it. (Recent Sony, Canon, Nikon, etc cameras all support the format as well.)
