The Best Free Lottie Animation Resources for Developers in 2025

Lottie has become the standard for animations in modern web and mobile apps. Here's a curated list of the best free resources — libraries, tools, and communities — for developers working with Lottie in 2025.

Free Lottie Animation Libraries

1. IconKing — 500+ Free Animated Icons

URL: iconking.net/all-assets?type=lottie&price=free

500+ free Lottie animations covering:

• UI icons (arrows, checkmarks, loaders, toggles)
• Social media icons (animated)
• Business and finance illustrations
• Food, travel, and lifestyle icons
• Country flags (animated)

All free to download. No account required for most assets. Each animation comes as both Lottie JSON and the newer .lottie format.

What's unique: IconKing also has static SVG versions of many of the same icons — so you can use the static SVG as a fallback while the Lottie plays.

2. LottieFiles Community

URL: lottiefiles.com

The largest community-driven Lottie library. Thousands of animations — some free, many premium. The free tier is still extensive. Strong on character animations, loading indicators, and UI micro-interactions.

3. Icons8 Animated Icons

URL: icons8.com/animated-icons

Consistent style, high-quality animated icons. The free tier includes many useful sets. Good for product UI work.

Free Lottie Tools

Preview: IconKing Lottie Preview

URL: iconking.net/preview

Drag-and-drop any Lottie JSON or .lottie file to preview it instantly in the browser. No upload, no account. Shows the animation playing and lets you toggle loop/speed.

Use case: Before adding an animation to your codebase, use this to verify it looks correct and check frame counts.

Edit Colors and Speed: IconKing Editor

URL: iconking.net/editor

Free browser-based editor for Lottie files. Lets you:

• Swap colors to match your brand
• Adjust playback speed
• Retime keyframes
• Preview the result in real-time

No After Effects needed. This is the quickest way to adapt a Lottie file without touching the source animation.

Convert to Other Formats: Lottie to GIF/MP4

URL: iconking.net/tools/lottie-to-gif

Export Lottie animations to: GIF, MP4, WebM, SVG, WebP, APNG, or .lottie format.

Useful when you need to use a Lottie animation in an environment that doesn't support the Lottie runtime — like email, Slack, presentations, or social media.

LottieFiles Editor (Web)

URL: lottiefiles.com/editor

LottieFiles' own web editor. More full-featured than IconKing's but requires an account. Good for teams that need version control and sharing.

Lottie Runtime Libraries

lottie-web

URL: github.com/airbnb/lottie-web
Size: ~500KB minified

The original Lottie runtime for web. Maintained by Airbnb. Supports SVG, Canvas, and HTML renderers.

npm install lottie-web

@lottiefiles/dotlottie-web

URL: github.com/LottieFiles/dotlottie-web
Size: ~100KB

The newer, lighter runtime. Uses WebAssembly for rendering. Optimized for the .lottie format. Significantly smaller than lottie-web.

npm install @lottiefiles/dotlottie-web

Framework-specific packages

Quick Performance Checklist

Before shipping a Lottie animation in production:

• [ ] Verify file size — aim for under 50KB for icon-level animations
• [ ] Preview at target size — animations that look fine at 200px may look different at 40px
• [ ] Test loop behavior — check the loop start/end frames are clean
• [ ] Consider the .lottie format — ~80% smaller than JSON for the same animation
• [ ] Lazy load — don't bundle animation JSON with your main JS bundle
• [ ] Destroy on unmount — call anim.destroy() in cleanup functions to prevent memory leaks

Lottie vs Other Animation Formats

Bottom line: Use Lottie for anything in your app. Use GIF when you need universal compatibility (email, chat platforms).

Convert between formats easily with the free tools at iconking.net.
