libgif is unavailable as emscripten ports yet. Probably worth submitting a patch.

Need to check the Node.js support status. Node.js 15 only supports it with a flag --experimental-wasm-simd.

It would be great to add an example in the README of how to use it in with one basic example.

Thanks!

To make sure it's supported on various Node.js versions, particularly with #3.

as title , can I run encoder in browser ?

JPEG support is disabled because no libjpeg in emscripten-ports. Probably need to build libjpeg together.

This is pretty much exactly what I need, and I'd like to know how it's licensed, to know whether it's available to me

Thanks
