Lottie is a new open-source animation file format that allows you to build lightweight, scalable, and interactive animations. The file type is comprised of code that can be easily changed to alter how the animation looks and moves without needing to recreate the animation. The smaller file size — about 600% smaller when compared to the GIF — won’t weigh down your app or website. It allows for high-quality animations on multiple platforms and high resolutions by mixing vector and raster elements.
