Lottie Animations & Lottie Preview Tool

Lottie animations have transformed how designers and developers bring interactive, lightweight animations to life on web and mobile platforms. With the rise of Lottie, the need for fast, intuitive tools to preview, test, and customize animations in real time has grown significantly.

That’s where our tool, Lottie Preview by The Lottie Company, comes in. Whether you’re a developer testing animations for Android, or a designer creating effects animations in After Effects, this platform is designed to enhance your workflow.

What is Lottie?

Lottie is an open-source animation framework developed by Airbnb that renders After Effects animations in real-time on web and mobile devices. It uses JSON-based files exported via the Bodymovin extension, making complex animations lightweight and easily scalable.

Since Lottie was introduced, it has become a standard in UI animation for websites, apps, and digital interfaces. Designers and developers use Lottie to create loading indicators, onboarding animations, icon transitions, and more.

Unlike traditional video or GIF formats, Lottie files are vector-based, resolution-independent, and smaller in size, making them perfect for responsive, high-performance projects.

What is a Lottie JSON File?

A Lottie JSON file is a specially structured JSON file that contains all the necessary information to render an animation — shapes, layers, timing, colors, transformations, and effects. These files are exported from After Effects using the Bodymovin extension.

Developers and designers can preview Lottie JSON files, test animations, and implement them into their apps without needing to re-code or rasterize their visuals. These files support interactive animations and allow for real-time customization—an essential feature in modern design workflows.

Why Use Lottie Animations in Modern Web/App Design?

  • Cross-platform support: Runs on iOS, Android, and all major web browsers.
  • Lightweight: Smaller file sizes than video or GIF.
  • Customizable: Change visuals without editing the original animation file.
  • Real-time rendering: Instant preview and feedback.
  • Enhanced UX: Boosts engagement with smooth, scalable animations.

Designers and developers now rely heavily on Lottie animations for web, apps, and cross-device interfaces due to their flexibility and visual appeal.
