iOS HEIC Performance
While HEIF turns out to be much more efficient as a storage medium, converting that stored data into a bitmap (and vice versa) is a process that’s much slower than using a JPEG. Therefore, we decided not to switch to HEIF in the cache for the time being and to reevaluate on future OSes and hardware. For other use cases, like storage of camera captures, network transmissions, or any other such instance where the size needs to be as small as possible, HEIF is indeed a great option. We hope that with improved hardware in the future, HEIF will become a viable option for our use case as well.
