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)
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

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
| Format | File Size | Quality | Interactivity | Email/Slack |
|---|---|---|---|---|
| Lottie JSON | Small | Vector | Yes | No |
| .lottie | Very small | Vector | Yes | No |
| GIF | Large | Bitmap | No | Yes |
| MP4 | Medium | Bitmap | No | No |
| SVG+CSS | Tiny | Vector | Limited | No |
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.
