Convert Lottie to WebM

WebM is the open, royalty-free video container built for the web: VP9 inside it compresses better than H.264 at the same visual quality, and Chrome, Edge, and Firefox play it natively with no plugin. To convert: drop your Lottie into Lotiqlab, open the Export panel, choose Video, set the format to WebM, and download. Rendering and encoding happen in your browser with WebCodecs, so the file is never uploaded.

How it works

  1. Drop your Lottie .json or .lottie onto the canvas below, or paste a URL to load it.
  2. Set the canvas background colour you want baked into the video — video has no transparency, so a transparent canvas exports as white.
  3. Open the Export panel, choose the Video tab, and set the format to WebM, then pick a resolution, framerate, and loop count.
  4. Hit export — Lotiqlab renders every frame and encodes VP9 in your browser, then downloads the .webm file.

By the numbers

Royalty-free
WebM and VP9 are open formats with no licensing fees, unlike H.264, which is why browsers ship them natively
0 uploads
Frames are rasterized and encoded locally with the browser's WebCodecs VideoEncoder — nothing is sent to a server
Up to 4K
Export at 144p through 2160p at 24, 30, or 60 FPS, with the loop count you choose

Frequently asked questions

Can a WebM export keep the transparent background?

Not from Lotiqlab today. The WebM container can carry an alpha channel, but Chromium's WebCodecs encoder does not implement alpha encoding for VP8 or VP9, so a transparent canvas is flattened onto white just as it is for MP4. If you need genuine transparency, keep the animation as a Lottie and let the player composite it over your page.

WebM or MP4 — which should I use?

Use WebM for web embeds: it is open, royalty-free, smaller at the same quality, and Chrome, Edge, and Firefox play it natively. Use MP4/H.264 for maximum compatibility, for social platforms, and for editors like Premiere and After Effects, which handle H.264 far more predictably.

Which browsers can export WebM here?

Export uses the WebCodecs VideoEncoder, which needs a Chromium-based browser such as Chrome or Edge 94+. Lotiqlab falls back to VP8 if VP9 encoding is unavailable, and tells you up front if the browser cannot encode video at all.

Is the exported WebM watermarked?

No. Every export from Lotiqlab is watermark-free and free of charge, with no signup and no upgrade prompt.

Is my animation uploaded to a server?

No. Lotiqlab is 100% client-side: the Lottie is rendered to canvas frames and encoded to WebM in your browser, so the file never leaves your machine.
