Free Online Lottie Previewer
A Lottie file can look different depending on size, background, playback speed, and implementation. This free Lottie previewer helps you test JSON and dotLottie animations before adding them to a website, mobile app, landing page, dashboard, or prototype.
Simply upload your Lottie JSON or .lottie file, paste animation JSON code, or import a file from a URL. The preview will load instantly so you can inspect the animation, check timing, scrub through frames, test loop playback, and make sure everything works as expected.
How it works
Start with a local JSON or dotLottie .lottie file that you want to inspect before implementation.
Preview raw JSON instantly without saving a separate file first.
Load a hosted animation and test it directly in the browser.
Check playback, timing, loop behavior, and backgrounds before using the file in your project.
Features
Test your Lottie animation online without installing extra software and check how it plays before publishing.
Upload JSON, upload .lottie, paste raw JSON, or import a hosted file URL.
Move through the animation frame by frame to inspect timing, motion, easing, and visual issues.
Preview your Lottie animation on different backgrounds to make sure it looks clean on real UI layouts.
Test how loading animations, progress indicators, animated icons, and continuous UI effects behave when repeated.
Once your animation looks correct, use it in your website, app, product interface, or design handoff.
Use cases
Designers can use this Lottie previewer to test animations before sharing them with developers or clients. Upload your Lottie JSON or .lottie file and check the motion, background contrast, loop behavior, and final playback quality in one simple browser tool.
Developers can quickly inspect Lottie files before adding them to React, Next.js, Vue, mobile apps, or product interfaces. Upload JSON or dotLottie, paste JSON code, import a file URL, preview playback, and confirm that the animation is valid before using it in your project.
Opening a Lottie JSON file directly in a browser or code editor does not show how the animation actually plays, and .lottie packages need to be unpacked before preview. A Lottie previewer turns the file into a live animation preview, helping you check motion, timing, looping, size, and visual quality before publishing.
This saves time for designers, developers, marketers, and product teams working with Lottie animations.
