Google's new editing tools can automatically touch up images or perform tricks such as erasing people from photos or creating animated GIFs stringing together multiple images to make it seem like the subject of a picture is moving.
Another feature will create a short movie set to music when a user selects different videos and pictures to mix together.
Snapseed, a Google-owned mobile application that competes against Facebook Inc.'s Instagram photo app, also is getting a new filter to improve the appearance of landscapes and structures.
Google has been focusing on building better image-management tools because a growing number of people are posting videos and photos online on social networking services.
About 54 percent of Internet users now post their own pictures or video online, according to a recent survey by the Pew Research Center.
Google says about 1.5 billion photos are being shared on Plus each week. Facebook recently said about 350 million pictures are being shared per day, or more than 2.4 billion per week. Millions more are shared on Instagram, which Facebook bought last year.
Snapchat also has become a popular spot for sharing photos, especially among people between 18 and 29 years old, according to Pew's survey. Unlike Google Plus, Facebook and other services, Snapchat wipes out the pictures once they have been viewed.
