One of the biggest hurdles in moving to Google Photos is getting your old library uploaded from where it is now.
With the ubiquity of Dropbox throughout multiple platforms and its great automatic uploading from your phone and desktop, there’s a decent chance you’ve used it to back up your photos. Whether you have a Dropbox folder structure with a defined hierarchy of categorization or several folders spread all about from various times, it’s still going to be a hassle to drag-and-drop individual folders out of Dropbox and over to Google Photos.
Thankfully with just a few steps and a couple of desktop applications you can let your computer do the work for you, pulling images from Dropbox and then swiftly moving them up to Google Photos. We’re going to show you how.
