Google has announced that it has acquired online photo editing Web site Picnik.

Picnik, which allows users to crop, touch-up and add effects to  photos online and without having to download any software, announced the move in a blog posting on Monday.

In another post on the Google photos blog, Brian Axe, Product Management Director, said that while the move won't result in immediate changes to the Picnik service, users can expect new features in the future.

“We're not announcing any significant changes to Picnik today, though we'll be working hard on integration and new features. As well, we'd like to continue supporting all existing Picnik partners so that users will continue to be able to add their photos from other photo sharing sites, make edits in the cloud and then save and share to all relevant networks.

Picnik joins the list of companies that Google has recently acquired, including social networking start-up Aardvark and mobile application reMail.
