Learn LOTTIEFILES with Real Code Examples

LottieFiles allows developers and designers to export After Effects animations to JSON and render them natively on web and mobile.

Supports multiple platforms including iOS, Android, React Native, Flutter, and the web (via lottie-web).

Animations are vector-based, scalable, and lightweight compared to GIFs or videos.

Interactive animations can respond to user input, scroll, and other events.

The Lottie ecosystem includes tools for previewing, sharing, and integrating animations seamlessly into projects.

Lottie vs GIF: Lottie is vector, smaller, scalable

Lottie vs CSS animations: Lottie allows complex After Effects animations

Lottie vs Anime.js/GSAP: Lottie uses JSON-based vector playback, GSAP animates properties

Lottie vs PixiJS: PixiJS is rendering engine, Lottie is animation format/player

Lottie vs Bodymovin manually: Lottie provides libraries for easy playback and interactivity
