Apply all optimizations and write to a given file (takes more time, but generates optimal code)

wasm-opt -O4 input.wasm [-o|--output] output.wasm

Optimize a file for size

wasm-opt -Oz input.wasm [-o|--output] output.wasm

Print the textual representation of the binary to console

wasm-opt input.wasm --print
