Why convert Lottie to WebM?
True transparency (VP9 alpha)
Unlike MP4, WebM with VP9 encoding supports a full alpha channel. Your animation stays transparent — perfect for overlaying on any website background or hero section.
20–40% smaller than MP4
VP9 compression is significantly more efficient than H.264. A Lottie animation that would be 500KB as MP4 might be only 300KB as WebM — meaningful savings at scale.
97%+ browser support
Chrome, Firefox, Edge, Opera and (since 2021) Safari all support WebM. With a modern user base you can safely serve WebM as the primary format.
Runs entirely in your browser
Your animation is rendered locally using the lottie-web canvas renderer and recorded by MediaRecorder. Nothing is uploaded — your file stays on your device.
Seamless loops
The converted WebM loops seamlessly, matching the original Lottie animation behavior exactly — no jump cut, no flash between loops.
Privacy first
Your animation file never leaves your browser. Client-side rendering means zero server uploads — complete privacy by design.
