Convert Lottie to WebM
Export a Lottie animation as a WebM video — smaller than GIF, with support for transparency.
How it works
- 1Upload a Lottie file (.json, .lottie, or .tgs), or try the example
- 2Adjust frame rate, quality, resolution and transparency
- 3Export to any format — or optimize and repackage as dotLottie
Nothing is uploaded. SVG output uses SMIL and needs no JavaScript; APNG and WebM keep the full color and transparency GIF can't.
About converting Lottie to WebM
WebM (VP9) is the web-native video format: significantly smaller than GIF at similar quality, widely supported across modern browsers, and — unlike MP4 — able to carry an alpha channel for transparent video overlays.
That makes WebM the best all-round choice when you need real video rather than an animated image: hero backgrounds, transparent overlays, and lightweight embeds. Encoding runs locally through the WebCodecs API. Where a browser supports VP9 alpha, transparency is preserved; otherwise it falls back to a solid background automatically.
Which format should I use?
| Format | Type | Transparency | Color | Best for |
|---|---|---|---|---|
| GIF | Animated image | 1-bit (hard edges) | 256 colors | Email, chat, universal support |
| APNG | Animated image | 8-bit (smooth) | Full 24-bit | Icons, logos, quality over size |
| WebM | Video | Yes (VP9 alpha) | Full | Small web video, transparent overlays |
| MP4 | Video | None | Full | Social, ads, video editors |
| SVG | Vector (SMIL) | Yes | Full | Runtime-free embeds |
| PNG / WebP | Still image | Yes | Full | Posters, thumbnails, placeholders |
Frequently asked questions
Does WebM support transparency?+
Yes, where the browser supports VP9 alpha. If it doesn't, the export falls back to a solid background — detection is automatic.
WebM or MP4 — which should I use?+
WebM is smaller and supports transparency, ideal for the web. Use MP4 when a specific tool or platform requires H.264.
Is my animation uploaded?+
No. Everything runs entirely in your browser — your file is never uploaded to a server.
