Selected JSON files are parsed in your browser and are not intentionally uploaded to an application server or stored in a product database.

Click the "Select File" button or drag a .json file onto the viewer. The tool checks for a Lottie-style JSON structure; advanced features and external assets may still require platform-specific testing.
The selected JSON is parsed in your browser and rendered with lottie-web. Load time and playback depend on file complexity, referenced assets, browser, and device.
Review dimensions, timing, layers, static complexity signals, platform-sensitive features, and starter integration code before testing in your own application.
Selected JSON files are parsed client-side and are not intentionally uploaded to an application server or stored in a product database. A file that references external images or fonts can still cause your browser to request those resources.
Powered by lottie-web, the viewer avoids a separate file-processing round trip. Actual load and playback performance varies with file complexity, assets, browser, and device.
The interface adapts to current desktop, tablet, and mobile browsers. Very large or complex animations may be limited by memory, renderer support, or device performance.
Inspect metadata, layers, playback, backgrounds, heuristic performance signals, compatibility flags, and code snippets, then validate the result in the target app and runtime.
Lottie is an open-source animation file format that renders vector-based animations in real time. Created by Airbnb, Lottie animations are exported as JSON data from tools like Adobe After Effects using the Bodymovin plugin.
Unlike a frame-by-frame raster format, Lottie stores animation instructions as structured data and can expose playback controls. File size and scalability still depend on embedded images, effects, and export choices.
Lottie player libraries are available for web, iOS, Android, and other environments. Feature support differs by runtime, so a web preview should be followed by testing on every target platform.
