Would be nice to get the ability to convert to HEIF, Apple’s default image format available in iOS 11 / macOS High Sierra and higher.
Currently there is no place to use except in the OS. NO browser supports this. Even if RW used the format it would have to be converted on export/upload. Not really prime time yet. "heif" | Can I use... Support tables for HTML5, CSS3, etc
When you assume my request was in the context of RW / a browser then I understand your response.
But I am using as a standalone app on my computer, where storing images in HEIF would be ideal.
