After 4+ years of learning and R&D in the Lottie format, we built an optimizer to reduce scripts and images within a Lottie, remove unused tags and optimize code, and we further added a zipped (www.dotlottie.io) layer on top of it.
LottieFiles significantly optimizes and reduces your animation's file size and maintains your original animation for you to download anytime.
Increased page load speed and reduced bandwidth will impress any developer. However, shipping an optimized Lottie remains the same as before. Libraries here: Web, iOS, Android, interactivity
