Apple has just released 10.13.4, which includes support for HEIC / HEIF encoding (support for reading HEIC was introduced in 10.13). And if you've already updated to Acorn 6.1, the option to export your image as HEIC will now appear for you in the Web Export window. How awesome is that?
HEIC is a next generation image format which Apple added to MacOS 10.13 and iOS 11. It is also the new native format for taking pictures with the latest iPhones. It gives better compression for the same image quality when compared to JPEG. It's a nice format.
But what if you want to batch export a bunch of images to this new format? Well, I'm working on something new and awesome in that area, and if you'd like to give it a spin just shoot me an email.
