How to Turn off saving to HEIC on iOS

It is possible to turn off iOS feature which saves Photo and Video files to HEIC. To do that you need to tap on Settings->Camera->Formats. There choose “Most compatible”. This will tell iOS to save all photos and videos to a format which is compatible with other software.
Current HEIC support is quite limited so even though choosing HEIC can save you some storage it may not be worth complexities in conversion.
