Tool guide

How to optimize Lottie JSON for delivery

Use the optimizer when a Lottie file is too large for a landing page, product dashboard, documentation article, or mobile app handoff. Smaller JSON can improve loading and make implementation easier to review.

Steps Recommended workflow
  • Paste or upload the Lottie JSON.
  • Choose safe cleanup options such as minifying JSON and reducing unnecessary precision.
  • Compare the optimized size with the original size.
  • Preview the optimized file before using it in production.
Limits What to check before publishing

Optimization should not change the visual intent, but aggressive cleanup can affect edge cases. Always test the optimized file in the actual player or framework that will ship it.

What should I check after optimization?

Check playback, loops, dimensions, transparency, file size, and whether the animation still matches the original.

Is minified JSON harder to debug?

Yes. Keep the original readable source for debugging and handoff notes.
