Lottie is a JSON-based animation format developed by Airbnb in 2017. It revolutionized how designers and developers work with motion graphics by bridging the gap between design tools like After Effects and production environments like web and mobile apps.
Here's why Lottie has become the go-to format for animations:
Lottie files are typically 10x smaller than GIFs and even smaller than most video formats.
Vector-based graphics look sharp on any screen size, from mobile phones to 4K displays.
Developers can manipulate animations programmatically – changing colors, controlling playback, or responding to user interactions.
Works on web, iOS, Android, React Native, Flutter, and more. One animation file, every platform.
LottieTools.app covers the entire Lottie workflow with specialized tools organized into categories. Whatever you need to do with a Lottie animation, we've got a tool for it.

Everything you need to know about Lottie animations and our tools.
Lottie is a JSON-based animation file format created by Airbnb. It allows designers to export animations from Adobe After Effects using the Bodymovin plugin and use them on websites, mobile apps, and other platforms. Lottie files are lightweight (often 10x smaller than GIFs), infinitely scalable without quality loss, and can be controlled programmatically with code.
Yes, absolutely! All tools on LottieTools.app are 100% free to use. There are no hidden fees, no premium tiers, and no usage limits. We believe powerful Lottie editing tools should be accessible to everyone, from students to enterprise teams.
No registration or login is required. You can start using any tool immediately – just open the page and upload your Lottie file. We don't collect personal information or require email signups. Your privacy matters to us.
No, your files never leave your device. All processing happens locally in your browser using JavaScript. We don't upload, store, or have access to your Lottie files. This is especially important for confidential projects – your animations remain completely private.
Use our Lottie Color Swapper tool. Simply upload your Lottie JSON file, and the tool will automatically extract all colors used in the animation. Click any color swatch to change it, preview changes in real-time, and download your modified file. No After Effects or design software needed!
Yes! We offer converters for Lottie to GIF, MP4, and WebM formats. Upload your Lottie JSON file, customize settings like frame rate, resolution, and quality, then download your converted file instantly. Great for sharing on platforms that don't support Lottie natively.
Use our Lottie Minifier tool. It removes unnecessary whitespace, metadata, and layer names from your JSON file. You can also optionally reduce number precision for even smaller files. Most animations see 30-60% size reduction without any visual quality loss.
LottieTools.app works in all modern browsers including Chrome, Firefox, Safari, Edge, and Opera. Since all processing happens client-side using JavaScript, you need a browser that supports ES6+. We recommend keeping your browser updated for the best experience.
