Happy Photo Exporter

Happy Photo Exporter provides a nice and simple solution for backup, export or sync of your image data.
Universal App (iPhone, iPad; also Mac Version available).

SELECT all photos, videos, favourites
EXPORT all data in one go, with easy restart and smart incremental data transfer handling (the app detects if files are already on target and skips duplicates).
IMPORT the image files with App (rebuilding Live Photos, rebuilding images with edits, again avoiding duplicates) or copy them to other device. File format compatible to macOS, Windows and Linux.
