LottieFyr is a browser-based tool for turning GIFs, MP4 videos, and static SVGs into lightweight Lottie animations.

I originally built it because converting an existing animation into a usable Lottie file often meant going back into After Effects or rebuilding the asset manually.

With LottieFyr, you can simply upload your asset, preview the result, and export it as .json or .lottie.

What you can do

• Convert GIF → Lottie
• Convert MP4 → Lottie
• Animate static SVG artwork
• Export JSON or .lottie files
• Preserve transparent backgrounds
• Control FPS, resolution and output quality
• Crop and optimize animations before export
• Preview the result directly in your browser

It's primarily built for UI/UX designers, frontend developers, mobile developers and anyone shipping motion on websites or apps.

The goal is simple: take animation assets you already have and make them easier to ship as lightweight, scalable Lottie animations — without needing a heavyweight motion-design workflow.

You can try the basic converter directly without logging in.

Feedback from fellow designers and developers is very welcome — especially around conversion quality, output size and workflows you'd like LottieFyr to support next.
