libvips for the browser and Node.js, compiled to WebAssembly with Emscripten.
libvips is a demand-driven, horizontally threaded image processing library. Compared to similar libraries, libvips runs quickly and uses little memory.

When the end of the pipe is connected to a destination, the whole pipeline executes at once, streaming the image in parallel from source to destination a section at a time. Because wasm-vips is parallel, it's quick, and because it doesn't need to keep entire images in memory, it's light.
