Facebook users can now transfer Facebook photos and videos to Google Photos without needing to download and reupload it. The feature is only available to Facebook users in Ireland for now, as a test, and expected to be available to the rest of the world in early 2020. Facebook built using the Data Transfer Project, a universal data import/export protocol that aims to give users more control over their data and let them quickly move it between online services or apps whenever they want. DTP framework is comprised of three components that have been designed to let any service easily convert their proprietary data and authentication formats into a common format that must be usable by others.
