The handful of people who still knew Picasa was a thing can scratch that one off their list because Google is shutting it down. The Web-based photo and video management tool will phase out over the next few months so Google can throw more resources into Google Photos.
Google shutting down Picasa to focus on Google Photos
The company said in a blog post,
After much thought and consideration, we've decided to retire Picasa over the coming months in order to focus entirely on a single photo service in Google Photos. We believe we can create a much better experience by focusing on one service that provides more functionality and works across mobile and desktop, rather than divide our efforts across two different products.
Instead of leaving Picasa users high and dry, Google is making the transition to photos pretty easy: just log into Google Photos with your Google user name and password, and everything should be there waiting for you.
Google is ending support for the Picasa desktop app on March 15, although it will continue to work for the time being. Picasa's Web Album feature ends on May 1, after which albums can still be viewed but not edited.
The good news for Picasa users who haven't made the move to Google Photos yet is that you won't be left out in the cold when you really do have to make the switch—which is coming soon.
