Tool guide

How to validate a Lottie JSON file

Use this validator when a Lottie animation loads in one player but fails in another, when a developer receives a minified file with no context, or when a design handoff needs a quick structure check before implementation.

Steps Recommended workflow
  • Paste the Lottie JSON or upload the file from your computer.
  • Run validation and read the visible summary before sharing the asset.
  • Check the frame rate, dimensions, layers, assets, and any warnings that may affect runtime playback.
  • Keep the original file unchanged and save a reviewed copy only after the structure makes sense.
Limits What to check before publishing

This page checks practical JSON structure and common handoff issues. It does not replace visual QA in the final product screen, and it cannot guarantee that every third-party Lottie renderer will support every feature in the file.

When should I use it?

Use it before sending a Lottie file to a developer, uploading it to a website, or converting it into another format.

Does validation mean the animation is production ready?

No. Validation is one check. You should still preview the motion, test background contrast, confirm loop behavior, and review file size.
