Google just launched a new technology compression pictures called RAISR for Rapid and Accurate Super Image Resolution. The new technology is designed so that you can save your valuable data without sacrificing the quality of your photos.
The company claims that up to 75% less bandwidth will be used with RAISR, since it will process and analyze both low- and high-quality image versions. Once an image is analyzed, the algorithm learns what makes the best version superior and simulates the differences in the image with the lowest analysis. 
In essence, this is done by using machine learning and creation an Instagram-style filter that can trick your eye into thinking lower-quality images are on par with high-resolution variants.
Unfortunately, the technology will initially work only on Google+ where Google says it will support upscaling to over a billion images a week.
If you do not want to use Google+, you will have to wait a little longer because, according to the company, RAISR will be added to more applications in the coming months.
Hopefully this means we'll see it where it really is, see Google Photos.
