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.
About WebM
WebM is an open, royalty-free video format launched by Google in 2010 as part of the WebM Project. Based on the Matroska container, WebM pairs VP8, VP9, or AV1 video with Vorbis or Opus audio (typically 64-160 kbps). The format was designed specifically for HTML5 video delivery, offering efficient compression without patent licensing fees. Opus audio, in particular, achieves excellent quality at low bitrates—often matching MP3 quality at half the file size.

WebM files are commonly encountered from YouTube downloads (youtube-dl, yt-dlp), screen recorders, and web-based video tools. YouTube uses WebM as one of its primary delivery formats, making it a frequent source for audio extraction. While Chrome, Firefox, and Edge play WebM natively, other devices may lack support—extracting to MP3 or WAV ensures universal compatibility.
Frequently Asked Questions
Why convert Lottie to WebM instead of GIF?
WebM is a video format developed by Google that produces much smaller files than GIF for long or complex animations. It uses the VP9 codec for efficient compression while maintaining high visual quality.
For animations longer than a few seconds or with complex visuals, WebM is typically 90-95% smaller than equivalent GIF files. For maximum compatibility in email clients, convert Lottie to GIF instead.
Can I play WebM everywhere?
All modern browsers support WebM video playback, including Chrome, Firefox, Safari (since macOS Big Sur), Edge, and Opera. WebM is also supported on many social media platforms and messaging apps.
For maximum compatibility in email clients or older systems, GIF remains the safest choice. For static previews, try our Lottie to PNG converter.
How does WebM quality compare to GIF?
WebM produces much higher quality than GIF. The VP9 codec supports full 24-bit color with no palette limitations, smooth gradients, and alpha transparency—all while maintaining smaller file sizes.
The output quality is essentially identical to the original Lottie rendering, unlike GIF which is constrained to 256 colors per frame.
How long does Lottie to WebM conversion take?
Most Lottie files convert in under 10 seconds. The conversion renders each frame of the animation and encodes them into VP9 video, so longer or more complex animations take proportionally more time.
Batch processing runs files in parallel — converting 50 files takes roughly the same time as converting one.
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.
