Lottie is a JSON-based animation format introduced by Airbnb for high-quality vector motion on web and mobile platforms. Instead of storing pixel frames, a Lottie file stores animation instructions that are rendered by a runtime player.

Lottie is ideal for product UI animations and app interactions, but it is not universally supported in email clients and social apps. Converting to GIF improves compatibility for broad sharing workflows.
WebP is Google's modern image format offering both lossy and lossless compression modes, plus alpha transparency and animation support—essentially combining the best features of JPEG, PNG, and GIF. Announced in 2010, WebP typically delivers 25-35% smaller files than JPEG at comparable quality using VP8 or VP8L compression. All major browsers now support WebP, making it a practical choice for web optimization.
Authoritative reference: WebP Documentation (Google)
WebP strikes an excellent balance between compression efficiency and ecosystem maturity. It's widely adopted for web delivery, supported across all modern browsers (Chrome 32+, Firefox 65+, Safari 14+, Edge 18+), and offers better compression than JPEG/PNG without the encoding overhead of AVIF.
CMS support: WordPress 5.8+ (July 2021) supports WebP natively. Most modern CMS platforms and CDNs (Cloudflare, Akamai, Fastly) can automatically serve WebP to compatible browsers via content negotiation.
Email limitation: Most email clients (Outlook, Gmail web, Apple Mail) do not support WebP. Always use JPG or PNG for email images, or provide a JPG fallback via <picture> elements in HTML emails.
Frequently Asked Questions
Why WebP?
WebP is a modern image format that supports both static and animated content with significantly smaller file sizes than GIF. Animated WebP files typically achieve 50-80% smaller file sizes while maintaining full 24-bit color and alpha transparency.
WebP was developed by Google and is ideal for web use where bandwidth and loading speed matter. Need maximum compatibility instead? Try our Lottie to GIF converter.
Browser support?
All modern browsers support animated WebP, including Chrome, Firefox, Safari, Edge, and Opera. Safari added WebP support in 2020, making it truly universal across all current browsers.
For the rare case of very old browsers, our Lottie to GIF converter produces universally compatible output.
File size comparison?
Animated WebP is typically 50-80% smaller than equivalent GIF files. This is because WebP uses more advanced compression algorithms (VP8/VP8L) compared to GIF's LZW compression.
For a typical Lottie animation, expect output files in the range of 20 KB-500 KB, compared to 100 KB-2 MB for GIF.
What animation properties are preserved?
Frame rate, duration, and alpha transparency are all preserved. The converter renders every frame of the Lottie animation at the original timing and resolution, producing a pixel-perfect animated WebP.
If you only need a single still frame, use our Lottie to PNG converter to extract a high-quality static image.
What's the difference between animated WebP and APNG?
Both formats support full-color animation with alpha transparency, but WebP typically produces smaller files. APNG uses PNG-based compression per frame, while WebP leverages inter-frame prediction for better compression.
APNG has slightly broader support in email clients. If email compatibility matters, try our Lottie to APNG converter.
What are the limits for this converter?
| Tier | Max File Size | Max Files/Batch | Parallel Processing |
|---|---|---|---|
| Guest/Free | 50 MB | 50 files | 3 at once |
| Pro | 1024 MB | 1000 files | 6 at once |
Note: File size limits are specific to this converter. Batch and parallel processing limits apply to all images converters site-wide. See all converter limits →
How are credits calculated for this conversion?
Cost: 1 credit per 50 frames
How it works:
- 1-50 frames: 1 credit
- 51-100 frames: 2 credits
- 101-150 frames: 3 credits
- 151-200 frames: 4 credits
Example: A 30-frame animation = 1 credit. A 300-frame animation = 6 credits.
Why per-frame? Each frame requires individual rendering and encoding. Longer animations with more frames need proportionally more processing.
What are my daily and monthly credit limits?
Credit allocations vary by account tier:
| Tier | Daily Limit | Monthly Limit |
|---|---|---|
| Guest | 100 credits/day | — |
| Free | 100 credits/day | — |
| Pro | — | 12,000 credits/month |
Daily credits (Guest & Free tiers) reset every day at midnight UTC. Monthly credits (Pro) reset on your billing cycle date.
Note: With 1 credit per 50 frames, short animations under 50 frames cost 1 credit each. Pro users can convert thousands of animations per month.
