What is Lottie JSON (.json)?

The Lottie JSON format is a lightweight file structure generated by the Bodymovin exporter for Adobe After Effects in 2015. It serializes keyframes, vector paths, and property data into human-readable JSON so that animations can be rendered programmatically on the web, iOS, Android, and connected devices. A single Lottie JSON file usually references additional assets—such as embedded images or fonts—that the player interprets at runtime. Because the data is vector-based, files remain small and scale sharply without losing quality, making the format ideal for user interface motion, marketing micro-interactions, onboarding flows, and product education sequences.

Teams adopt Lottie JSON to replace heavyweight GIF or video exports. Developers can load the JSON payload into the open source lottie-web or lottie-react-native libraries and trigger animation playback with code. This approach keeps interfaces responsive and accessible because vector animation supports reduced motion settings, dynamic theming, and runtime control. Within this Lottie JSON to .lottie preview tool, you can validate that the JSON describes the correct timing, easing, and layering before converting it into alternate packaging formats or shipping it directly to production applications.

What is the .lottie format?

The .lottie extension is a newer packaging specification introduced by the LottieFiles team in 2020 to simplify distribution. Rather than shipping a Lottie JSON file alongside separate images, the .lottie archive bundles all assets, metadata, and previews into a single compressed file similar to a ZIP container. The structure is built on top of the Lottie player specification, which means runtime behavior matches the original JSON while reducing the network requests required to load an animation on the web or inside mobile applications.

Because .lottie archives include manifest data and theme definitions, teams can store multiple colorways or playback instructions in one package. The Lottie JSON to .lottie preview page lets you confirm that these compressed bundles maintain the same vector fidelity, easing curves, and accessibility controls as the source JSON. Motion designers who collaborate with engineers on design systems rely on the format to standardize delivery, and this viewer ensures that conversions remain faithful regardless of the platform handling playback.

How to Convert Lottie JSON to .lottie?

Follow these steps to review and refine your Lottie JSON to .lottie workflow. Each stage helps confirm that the converted animation stays faithful to the motion design intent before you publish it to production apps or marketing channels.

1
Upload your Lottie JSON or .lottie file
Drag and drop a Lottie JSON export (.json) or a compressed .lottie bundle into the upload area. You can also click the button to browse your device if you prefer manual selection.
2
Inspect the animation preview
The viewer renders your Lottie JSON to .lottie preview instantly using the official lottie-web player. Playback loops automatically so you can evaluate frame rate, easing, and compositing from the first frame to the last.
3
Review layer and color fidelity
Use the controls to pause on important frames and confirm that vector paths, gradients, masks, and blend modes survived the conversion pipeline from After Effects or Rive to Lottie JSON and .lottie.
4
Adjust export settings if needed
If anything looks off, return to your authoring tool to tweak Bodymovin or LottieFiles export options. The Lottie JSON to .lottie workflow may require toggling rasterized layers or reducing complexity for mobile playback.
5
Download or share the validated file
Once the preview matches expectations, keep the verified Lottie JSON file or package it into the .lottie format for distribution to developers, marketing teams, or stakeholders.

Lottie JSON to .lottie tools and resources

Beyond simple playback, the viewer provides context that helps you make smarter production decisions. Combine it with your existing pipeline to shorten review cycles and keep performance targets in check.

Compression insights: Compare file sizes between Lottie JSON and .lottie exports to pick the right asset for high-traffic screens or bandwidth-constrained markets.
Platform parity testing: Validate that animations converted with Bodymovin or LottieFiles behave the same inside iOS, Android, and web players.
Accessibility review: Use the preview to evaluate reduced motion settings and confirm the animation respects user preferences before deployment.
Developer handoff notes: Document loop behavior, playback triggers, and fallback assets while everyone watches the same Lottie JSON to .lottie preview.

Frequently asked questions

Explore detailed answers about Lottie JSON to .lottie workflows, privacy practices, and best practices for distributing lightweight animations across platforms.

How do I open a Lottie JSON file?: Lottie JSON files open in the vizGPT Lottie JSON to .lottie previewer, in LottieFiles, or within codebases that implement the lottie-web, lottie-react, or lottie-ios players. You can also re-import the file into After Effects with the Bodymovin extension to make adjustments.
What programs can read .lottie bundles?: The .lottie extension is supported by modern versions of LottieFiles, Lottie players for iOS and Android, and libraries such as lottie-react-native. It packages assets and JSON into a single compressed file for faster delivery.
How do I convert Lottie JSON to .lottie offline?: To convert Lottie JSON to .lottie offline, export your animation with the LottieFiles desktop app or run the official Lottie CLI, which wraps the JSON, assets, and metadata into a .lottie archive. After conversion, import the file into this viewer to confirm that playback matches the original JSON.
Can I preview Lottie JSON without installing software?: Yes. Drag a file into this browser-based Lottie JSON to .lottie preview tool. Rendering happens locally, so you do not need to install After Effects, the LottieFiles app, or other software to validate your animation.
What is the maximum file size supported?: The preview is limited only by your browser memory. Lottie JSON files under 10 MB and .lottie bundles under 15 MB perform best, but larger files typically load as long as your device has sufficient resources.
Does converting Lottie JSON to .lottie reduce quality?: No visual fidelity is lost when exporting properly. The .lottie format compresses assets but retains the same vector data. Use this previewer to compare both outputs and ensure gradients, masks, and effects match the source animation.
Can I batch convert multiple animations?: While this viewer handles one file at a time, you can convert batches using LottieFiles automation or command-line scripts. Upload each resulting Lottie JSON or .lottie file here for a quick human-in-the-loop check.
Are my Lottie JSON files uploaded to a server?: No. The Lottie JSON to .lottie preview process runs entirely in your browser. Animations stay on your device, and refreshing the page clears them from memory.
Can I convert .lottie back to Lottie JSON?: Yes. Use the LottieFiles CLI or online tools to unpack a .lottie archive back into its JSON and asset components. After extraction, re-upload the JSON to this previewer to verify nothing changed during the round trip.
What other formats can Lottie JSON export to?: Besides converting Lottie JSON to .lottie, teams frequently generate GIFs, MP4 previews, or WebM videos for social channels. Always check the animation in its native Lottie format before producing rasterized derivatives.
