Are my Lottie files uploaded to a server?

No. TinyLottie processes everything locally in your browser using JavaScript and WebAssembly. Your files never leave your device, ensuring 100% privacy.

What is dotLottie format?

dotLottie is an open-source binary format that packages Lottie JSON and its assets into a single ZIP-compressed .lottie file. It is typically 30–40% smaller than raw Lottie JSON and is supported by LottieFiles, DotLottie players, and most modern animation libraries.

How do I reduce Lottie file size in Webflow?

Export your Lottie JSON from After Effects using Bodymovin, then upload it to TinyLottie at tinylottie.com. TinyLottie removes metadata, rounds coordinate precision, and compresses embedded images. After optimization, upload the smaller file to Webflow to improve Core Web Vitals scores.

How do I optimize Lottie animations for React Native?

Use TinyLottie to compress your Lottie JSON before bundling it in your React Native project. TinyLottie removes runtime-unnecessary properties (layer names, match names) and rounds float precision, reducing JS thread parse time. For best results, also consider the dotLottie output format supported by @lottiefiles/dotlottie-react-native.

How do I compress After Effects JSON exports?

After exporting from After Effects using the Bodymovin plugin, upload the JSON file to TinyLottie. TinyLottie strips Bodymovin metadata (nm, mn, cl properties), rounds float precision from 6 to 3 decimal places, and converts embedded raster assets to WebP. Most AE exports see 50–85% file size reduction.

Yes. TinyLottie is free forever for Lottie and dotLottie files up to 3MB. A one-time Lifetime PRO upgrade ($99) unlocks files up to 50 MB with no subscriptions.

Frequently asked questions

What is the difference between Lottie JSON and dotLottie?

Lottie JSON is the plain-text animation file exported by Bodymovin and similar tools. dotLottie (.lottie) is a ZIP archive that contains the same JSON animation plus a manifest and any image assets, compressed with Deflate. Players such as dotlottie-web and the LottieFiles players load it directly.

How much smaller is a .lottie file?

It depends on the animation. Vector-heavy JSON compresses very well: in our test with a real animation from LottieFiles' public dotLottie samples, a 45.7 KB JSON became a 4.6 KB .lottie (about 90% smaller). Animations that are mostly embedded images shrink less, because images are already compressed — use the Lottie Compressor to convert those images to WebP.

Can I convert a .lottie file back to JSON?

Yes. Drop a .lottie file and TinyLottie extracts its first animation as JSON. Any images stored in the archive are inlined as base64 data URIs, so the JSON works on its own with lottie-web.

Is my animation uploaded anywhere?

No. The conversion runs entirely in your browser using JavaScript. The file never leaves your device.

Is the converter free?

Yes — conversion is free for files up to 50 MB, with no account required.
