I could not find it in the searches, so I open this topic.
My plan was to use Seafile to backup all my photos from an iPhone via wifi to my server (My Cloud Home with Debian).
In a first test I tried uploading all photos from an iPhone.
It seems that all HEIC photos are converted to JPG by the app. I could not find the option to stop this.
Is there any way to switch this off? Or will HEIC support be added to the app in the (very) near future?
