Re: How do I move photos from Dropbox to Google photos.
Do you have Dropbox installed and syncing to your computer? If so, the photos are already on your computer. Just upload them to Google using whatever method they provide. If you don't have Dropbox installed and the photos aren't already on your computer, you'll need to download them from Dropbox first.
Alternatively, you can use a third-party service, such as mover.io, to move files between cloud storage services.
