In a move that brings fierce competition to Facebook, the buyout sees the search engine giant get its hands on Instagram rival Snapseed.
Photo editing service Snapseed is available for iOS, Mac and PC. The iPad edition was named 'App of the Year' by Apple in 2011, and gained 9 million users in its first 12 months on the market.
"We are pleased to announce that Google has acquired Nik Software. For nearly 17 years, we've been guided by our motto, 'photography first', as we worked to build world class digital image editing tools," read a statement from Nik Software.
"We've always aspired to share our passion for photography with everyone, and with Google's support we hope to be able to help many millions more people create awesome pictures.
"We're incredibly grateful for all of your support and hope you'll join us on the next phase of our journey as part of Google."
Nik Software staff who worked on Snapseed will relocate to Google headquarters in Mountain View to integrate the service into the Google+ social network, The Verge reports.
An Android edition of Snapseed is said to be in the works for mobile phones and tablets running the operating system.
