# Preview Your Lottie Animation **Previous:** [Export Your Animation to Different Formats](https://aninix.com/guides/export-animation-formats) | **Next:** [Share Animation with Developer](https://aninix.com/guides/share-animation-with-developer) Before implementing your Lottie animation in your website or mobile app, it's crucial to preview it to ensure it looks and behaves exactly as expected. Aninix provides a dedicated Lottie preview tool for this purpose. ## Why Preview Lottie Files? Lottie files are vector-based animations that can behave differently in various environments. Previewing helps you: - **Verify Animation Quality:** Ensure smooth playback and timing - **Check File Size:** Confirm the animation loads quickly - **Test Interactivity:** See how the animation responds to user interactions - **Validate Compatibility:** Ensure it works across different browsers and devices ## Step-by-Step Preview Process ### Step 1: Access the Lottie Preview Tool Go to [app.aninix.com/lottie-preview](https://app.aninix.com/lottie-preview) to access the Lottie preview tool:  ### Step 2: Upload Your Lottie File Select your Lottie file to preview by clicking the upload area or dragging and dropping your `.json` file. ### Step 3: Preview Your Animation Your Lottie animation will load and you can preview it in the browser:  ## Preview Features The Lottie preview tool provides several useful features: - **Play/Pause Controls:** Start and stop your animation - **Playback Speed:** Adjust animation speed to test different scenarios - **Loop Controls:** Test single play vs. continuous loop behavior - **Frame-by-Frame:** Step through your animation frame by frame - **Responsive Testing:** See how your animation scales at different sizes ## What to Check During Preview ### Animation Quality - **Smooth Movement:** Ensure all transitions are fluid - **Timing Accuracy:** Verify animation timing matches your design - **Visual Fidelity:** Check that all elements render correctly ### Performance - **Loading Speed:** Note how quickly the animation loads - **File Size:** Check the file size for web optimization - **CPU Usage:** Monitor browser performance during playback ### Compatibility - **Browser Testing:** Test in different browsers if possible - **Scaling:** Verify the animation looks good at different sizes - **Loop Behavior:** Ensure proper looping if that's intended ## Troubleshooting Common Issues ### Animation Doesn't Play - Check file format (should be `.json`) - Verify the file isn't corrupted - Ensure proper export from Aninix ### Poor Quality or Missing Elements - Re-export with higher quality settings - Check that all design elements were included in the original export - Verify complex effects are supported in Lottie format ### Large File Size - Simplify complex animations - Reduce keyframe density - Consider using fewer colors or effects ## Implementation Tips Once you've confirmed your Lottie animation looks perfect: ### For Web Development - Use libraries like `lottie-web` or `@lottiefiles/react-lottie-player` - Consider lazy loading for performance - Test on actual devices and browsers ### For Mobile Development - Use platform-specific Lottie libraries (iOS: Lottie-ios, Android: lottie-android) - Test on different screen densities - Consider animation performance on older devices ## Next Steps Now that you've successfully created, exported, and previewed your Lottie animation, you're ready to implement it in your project! ### Ready to Share with Developers? - [Share animation with developer](https://aninix.com/guides/share-animation-with-developer) to generate ready-to-use CSS code and specifications - Learn how to [sync changes](https://aninix.com/guides/sync-changes) between Figma and your animations ### Want to Create More Animations? - [Import a new design](https://aninix.com/guides/import-design-to-aninix) to start fresh - Try [different animation techniques](https://aninix.com/guides/create-keyframe-animation) for variety - Experiment with [Quick Presets](https://aninix.com/guides/create-animation-with-presets) for rapid prototyping ### Need Different Formats? - Learn about [all export options](https://aninix.com/guides/export-animation-formats) available in Aninix - Consider GIF format for social media or email campaigns - Try MP4 export for video presentations --- - **Next:** [Share Animation with Developer](https://aninix.com/guides/share-animation-with-developer)
