HEIC photo format and your photos
If you have updated to IOS 11 on your iPhone or iPad you may remember being asked if you want to use a high-efficiency way of storing your photos. If you answered yes then your photos started to be stored in a new format HIEC.
This format allows much better compression without a reduction in quality to your photos This means you can store far more photos but like many things in life, there is a tradeoff. The HEIC format is such a new format, most photo software currently can’t read it.
The current versions of Mac OSX High Sierra and Windows 10 as of March 2018 can read it. If you don’t have either of these O/S’s you will have to install software to read them. Fortunately, there are several options that are free and very easy to install.
Another option if you don’t want to go to the trouble of finding conversion software is to store your photos as .JPG’s on your phone or tablet.
Do the following steps.
Tap Settings on iPhone
Select “Most compatible”
Since you should be backing your photos up anyway (see my guide on using Google Photos as a backup service) having photos that take up more space should not be a problem as you can backup and then delete older ones from your device’s photo stream.
