Google Photos is one of the easiest and best ways to back up all of the images you take with your phone. Today, Google announced a handful of new improvements for the service.

The most interesting of the new features is the ability to utilize artificial intelligence to automatically colorizes old black-and-white photos. Presumably, you’d take a picture of the old photo with your phone, and then Google Photos will analyze it and produce a colorized file of it.

In addition, Google says it can use AI to help separate subjects in photos or recognize images of documents and automatically convert them to PDF files. Another new feature will automatically suggest exposure adjustments and improvements to your photos.

For developers, Google has released new APIs that can plug into Google Photos services directly. Google says these tools and APIs will let developers build Google Photos search, upload, and sharing tools directly into their apps.

Photos is available on both Android and iOS, and it lets you back up pictures and video automatically for free. It also provides a number of intelligent categorization and organizational features, plus editing tools and photo book creation. Google did not say when these new features would be available in the Google Photos app.
