It seems to be quite popular to move away from custom build IT solutions to so called COTS - commercial of the shelf solutions. The idea being, that to software solution fulfil a functionality which long has been commoditized and standardized to such an extent that it offers no “competitive edge” nor core value to the business. For most companies and organizations the office suite would be a pretty safe bet for a piece of software which is magnificently suited for a COTS solution.
Google has come up with a nice new image format called webp. Currently support for this format is fairly limited, so if you need to use webp images else where it might be nice to convert them to a more widely supported format. To do the conversion, Google has made a small tool available called dwebp. The tool however does only seem to support conversion of a single image, not a batch of images.
