About this tool
Inspect Lottie JSON before handing it to engineering or shipping it in a landing page. Check size, layer complexity, and asset usage from one screen.
Lottie Inspector is useful when teams need more than simple playback and want to inspect the structure of an animation asset. It helps with debugging layers, assets, markers, and metadata before the file moves deeper into product or motion workflows.
- Shows canvas size, duration, frame rate, layer count, and asset count.
- Flags common delivery risks like image-heavy animations and long durations.
- Useful for design QA and developer handoff.
How to use Lottie Inspector
Load the Lottie JSON, review the structural details, and use the inspector output to confirm the file matches your implementation or optimization expectations. If the animation behaves unexpectedly in production, compare the inspector results with the working reference file so you can spot structural drift faster.
When this tool is useful
- Shows canvas size, duration, frame rate, layer count, and asset count.
- Flags common delivery risks like image-heavy animations and long durations.
- Useful for design QA and developer handoff.
Practical tips
Examples you can test
These examples show the kind of real input and reviewed output this tool is designed to support. Use them as a starting point before pasting your own production content, then compare the output with the destination system that will use the result. The goal is not only to produce a value, but to make the input assumptions, output format, and review step clear enough that the result can be trusted in a real workflow.
Inspect animation metadata
Example input
Lottie JSON with 120 frames at 60 fps
Expected output
Duration, frame rate, dimensions, and layer summary
Metadata helps confirm whether an animation fits the intended UI slot and playback duration.
Review layer complexity
Example input
Lottie file with many shape layers
Expected output
Layer and asset counts for performance review
Complex animations can affect rendering performance, especially on lower-powered devices.
Validation checklist
Run through these checks before copying the result into a CMS, codebase, spreadsheet, campaign, support ticket, or production document. Small formatting differences, unit assumptions, hidden whitespace, and platform-specific rules are common sources of mistakes in quick browser tools, so the final review should happen in the same context where the output will be used.
- Check dimensions, frame rate, and duration before shipping an animation.
- Review file size and layer count when performance matters.
- Preview the animation in the target app or browser context before publishing.
Why people use this tool
People search for Lottie inspection tools when they are troubleshooting or auditing animation assets, not just previewing them. The page is strongest when it makes internal structure readable enough for developers and designers to diagnose issues together.
