Free Lottie Converter Tools - Convert Video, GIF & More to Lottie JSON

Lottie is the JSON-based animation format that powers lightweight, scalable animations in iOS, Android, React Native, and web apps. But getting content into and out of Lottie format usually means expensive software, LottieFiles subscriptions, or manual After Effects work. Our Lottie toolkit converts video and GIF sources to Lottie JSON, and exports Lottie animations back to GIF or MP4 — entirely free, with no signup and no file uploads.

Convert video clips to Lottie with our MP4 to Lottie, MOV to Lottie, and WebM to Lottie converters — perfect for turning iPhone screen recordings, browser captures, and video assets into app-ready animations. Each lets you pick your exact clip range, frame rate, and output quality, with automatic frame deduplication to keep file sizes small.

Already have a Lottie animation and need to share it somewhere Lottie can't play? Our Lottie to GIF converter exports with transparent background support for Slack, docs, and email, while Lottie to MP4 produces hardware-accelerated H.264 video for social media, presentations, and video editors — both rendered with the official lottie-web engine for pixel-accurate results.

Once your Lottie file is built, run it through our Lottie Optimizer to strip the bloat that After Effects and conversion tools leave behind: full floating-point precision, layer names, generator metadata, and oversized embedded images. Typical files shrink 20-60% with no visible difference — critical for app bundle size and Core Web Vitals.

Before shipping any Lottie file — whether you converted it here, downloaded it from LottieFiles, or received it from a designer — use the Lottie Preview to check what you're actually working with: frame rate, frame count, layer count, and embedded image count, all without opening the JSON in a text editor. It's the fastest way to confirm a file plays correctly and catch an oversized animation before it reaches your codebase.
