Lottie optimizer and video export for Mac

Your Lottie is heavier
than it needs to be.

LottieGo strips out the metadata, hidden layers and extra decimal places your animation never uses. When someone asks for a video instead, it exports MP4, transparent MOV or GIF too.

macOS 14 or later Files stay on your Mac

What it does
to a real file.

We dropped in one Lottie and it came out 60.8% smaller. Then we exported the same file as MP4, MOV and GIF.

01 / WHAT IT DOES

The chores that come
after the animation.

You finished the animation. Getting it into an app, a slide deck or a chat thread is a separate job, and that's the part LottieGo handles.

01

Shrink the JSON

Removes redundant data and cuts decimal places the animation doesn't need. You see the old and new file size side by side, with a preview to check nothing broke.

OPTIMIZE → PREVIEW → SAVE
02

Export it as video

For when marketing wants an MP4, your video editor wants a clip with a transparent background, or you just need a GIF to drop into a chat.

MP4 / MOV / GIF
03

Run it in batches

Drop in a whole set of files and they're optimized together. Free handles 5 per batch. Pro has no cap.

DRAG → OPTIMIZE ALL

02 / EXPORT

Turn a Lottie into
MP4, MOV or GIF.

Pick a format, set the output scale and background, and export. The free version includes 3 exports so you can see how it works. Pro has no limit.

FORMATS
.mp4

Plays almost anywhere

H.264 opens in Keynote, PowerPoint and most social apps. MP4 can't be transparent, so you pick a background color.

03 / ALSO IN THE APP

Other things worth knowing.

NATIVE MAC APP

Preview every result

Each optimized file plays next to its new size, and you pick which ones to save. Animations with expressions or fine detail are worth a quick look first.

Your originals are safe

Save a new copy with your own filename suffix, or replace the original with a local backup you can restore from the app.

Shortcuts and URL automation

Pro adds Apple Shortcuts actions and lottiego:// URLs, so a job you repeat every week can run from a shortcut or a script.

A proper Mac app

Native UI with light and dark mode that follows your system setting. You can copy optimized JSON straight to the clipboard without saving a file.

04 / TRY IT HERE

Shrink a Lottie
right here.

Same interface as the Mac app, free, with nothing to install. Drop in a Lottie JSON file and download a smaller copy. The video export panel is a demo.

Your file stays in the browser tab. Nothing is uploaded and you don't need an account.

or drop your own JSON

The JSON optimization here is real. The video export only simulates the Mac app and doesn't use up any of its free exports.

Export Video celebrate.json

Widely compatible. No transparency.

Frame Rate
Background

A solid background is required for this format.

Demo only. No video file will be created.

FAQ

Common questions.

What can I do for free?

Optimize up to 5 JSON files per batch, as often as you need. Preview animations, copy JSON, and save a new file or replace the original with a local backup. The Mac app also includes 3 successful video or GIF exports per Mac. JSON optimization remains available after those exports are used up.

What do I get with Pro?

Pro removes the JSON batch-size limit, gives you unlimited MP4, transparent MOV and GIF exports, and enables Apple Shortcuts and lottiego:// URL automation. It is a one-time in-app purchase, not a subscription. Check the Pro window in the app for the current price in your region.

How do the 3 free exports work?

The allowance counts successfully exported files, not export sessions. Exporting 3 animations in one batch uses all 3 exports. Failed or canceled exports do not count. The allowance is shared across MP4, MOV and GIF on that Mac and does not renew daily or monthly. If a batch exceeds your remaining exports, select fewer files or get Pro.

Can I restore my Pro purchase?

Yes. Use Restore Purchases in the app with the Apple Account used to buy Pro. Apple handles the purchase and verification; you do not need a separate LottieGo account. Restoring Pro is different from replenishing the free export allowance.

What does LottieGo optimize?

LottieGo processes Lottie JSON files. It trims redundant metadata, removes supported watermark layers and unused hidden layers, and rounds numeric precision. Check the preview before using the result, especially for animations with fine detail or expressions.

What stays on my device?

The Mac app processes and exports files locally. The web optimizer also processes JSON in your browser without uploading your file. Its preview player is loaded from Lottielab’s CDN; animations that reference external images may load those images from their source.

Can I export an animation with a transparent background?

Yes. Choose MOV in the Mac app for HEVC with alpha. All 3 export formats are available within your free export allowance, and Pro removes the limit. MP4 and GIF require a solid background in LottieGo.

How is the web tool different from the Mac app?

The web demo optimizes and downloads real JSON files, but its video exports are simulations: no video file is created and no Mac export allowance is used. Pro-only options in the demo only show the interface; they don't give you Pro in the Mac app.

Will my original files be changed?

The web tool downloads a separate optimized file. In the Mac app, you choose between a new file and replacing the original. Replace mode creates a local backup, with a restore action available in the app.
