wasm-opt — Optimize WebAssembly binary files. More information: <https://manned.org/wasm-opt>.

Apply default optimizations and write to a given file

wasm-opt -O {{input.wasm}} {{[-o|--output]}} {{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]}} {{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
