Optimize WebAssembly binary files. More information: <https://github.com/webassembly/binaryen>.

  • Apply default optimizations and write to a given file:
    wasm-opt -O input.wasm -o output.wasm
  • Apply all optimizations and write to a given file (takes more time, but generates optimal code):
    wasm-opt -O4 input.wasm -o output.wasm
  • Optimize a file for size:
    wasm-opt -Oz input.wasm -o output.wasm
  • Print the textual representation of the binary to console:
    wasm-opt input.wasm --print
