Due to the fact that Windows and MacOS (previous to High Sierra) does not natively support the HEIC photo format, we implemented a possibility to convert HEIC photos to JPEG (for maximum compatibility).
Let us explain the decisions that we made on handling HEIC photos in the iBridge 3 app:
"Transfer Photos" feature (Manual transfer)
Transfer photos >> From Camera Roll to iBridge.
When you select individual photos (or groups of photos) in this area of the App, each of these photos will be converted from HEIC format to JPEG format during the copy function and copied to iBridge Photos folder on the iBridge 3 device.
Please note that "Convert HEIC to JPEG" is enabled by DEFAULT ON in the Settings area of the app, and you are free to disable it at your discretion.
“Auto backup” feature
Unlike the Transfer Photos feature, if you have enabled the Auto Backup feature, the app keeps the original .heic photo format during backup, and the images will NOT be converted into JPEG. If you want the Auto Backup feature to backup JPEG files only, we recommend that you change the default setting in your iPhone Camera Formats to Most Compatible, which will only save photo files in the JPEG format.
