There are a couple of different ways to decode a wasm file. The first, and simplest, is wasm2wat from the WebAssembly Binary Toolkit. This simply takes a binary wasm file and converts it into a human-readable text form (WAT). However, wasm is a pact and relatively low level binary format, and as a result, much of the information in the original code is lost. As a result, depiled WAT files may not be that easy to read.

More recently, the Chrome team launched wasm-depile, a tool that attempts to create a more readable depiled output using a pseudo language that is quite readable (for JavaScript developers).
