View and test Lottie JSON animations
Paste Lottie JSON or a URL above, then click Load Animation.
Paste a Lottie JSON URL or copy the raw JSON data directly into the text area and click "Load Animation". The player renders the animation in the preview area. Use the Play and Pause buttons to control playback. The tool supports standard Lottie JSON format exported from Adobe After Effects using the Bodymovin plugin. You can test animations from LottieFiles, Lordicon, or custom animations generated by your design team before integrating them into your web or mobile project.
Lottie is an open-source animation format exported from Adobe After Effects. It produces small, scalable vector animations that play smoothly in web browsers and mobile apps. Common uses include loading spinners, micro-interactions, and animated icons.
Animation preview before integration — Test Lottie animations in your browser before adding them to your website or app. Design handoff review — Designers can share Lottie JSON files with developers for preview without After Effects. Performance testing — Check animation performance and file size to ensure lightweight delivery. Educational purposes — Students and aspiring motion designers can examine Lottie animation structure by loading JSON files from various sources.
Keep file sizes small by simplifying shapes and reducing keyframes. Test on low-end devices to ensure smooth playback. Use reliable CDN hosting for low-latency delivery. Check browser compatibility for your target audience with appropriate fallbacks.
The player supports Lottie JSON files (.json). It does not support the older .aep (After Effects) format or dotLottie (.lottie) files. For dotLottie, use the official LottieFiles player.
Free Lottie animations are available at lottiefiles.com and lordicon.com. Search by keyword, then copy the JSON URL or paste the animation data directly.
Check that the URL points to a valid Lottie JSON file. Some animations may use features not supported by the browser player. Try a different browser or check the browser console for errors.
Several strategies can reduce Lottie file size significantly. Simplify your After Effects compositions by reducing the number of layers and shapes. Remove unused keyframes and avoid animating properties that change every frame. Use the Bodymovin plugin's built-in compression options during export. Convert solid-color shapes to simple vector paths instead of using complex masks. You can also use third-party tools like LottieFiles compression to further reduce file size without noticeable quality loss.
Yes, Lottie animations are widely used in production across major websites and mobile applications. To integrate them, include the lottie-web library in your project and use its JavaScript API to load and control animations. The library supports playback controls, event listeners, and responsive rendering. Lottie files are significantly smaller than traditional GIF or video alternatives, making them ideal for web performance. Many large companies including Airbnb, Uber, and Google use Lottie in their products.
