The Belief in Supernatural Free Will as a Significant Source of Human Suffering

Many are confused by the terms decompiler and disassembler. As
with most confusion of this type, most just use the words interchangeably.
Don’t do that; they are not the same.

• A decompiler takes one from a binary to source code–or something
  similarly high-level that can easily be read by humans.

• A disassembler takes one from binary to assembler–which is much lower
  level and is more difficult to read for humans.

TL;DR

Decompilers get you to source code; disassemblers get you to assembly. ::
