If you're considering using HEIF, beware. It was developed by the MPEG group and it really just a container around H.265 still image(s). Thus, like everything from MPEG, it is patent encumbered to hell. Want to make a product that comprehends HEIF files? Pay the piper! This isn't much different from why GIF needed to be abandoned or why people are trying to use alternate video formats: MPEG patent licensing fees are hobbling effect and a determent to open source work. So now MPEG-LA wants a tax on what used to be free JPEG images? I'm not impressed.
