Documentation Status Build Status Code Coverage Status PyPI Version

A Python library and tools providing easy access to the decompilation service through their public REST API.

You can either incorporate the library in your own scripts:

from retdec.decompiler import Decompiler

decompiler = Decompiler(api_key='YOUR-API-KEY')
decompilation = decompiler.start_decompilation(input_file='file.exe')

or you can use the provided script for stand-alone decompilations:

$ decompiler -k YOUR-API-KEY file.exe

Waiting for resources (0%)...                    [OK]
  Obtaining file information (5%)...             [OK]
  Unpacking (10%)...                             [OK]
  Initializing (20%)...                          [OK]
Done (100%)...

 - file.c

Either way, file.c then contains the decompiled C code:

$ cat file.c
// This file was generated by the Retargetable Decompiler
// Website:
// Copyright (c) 2016 Retargetable Decompiler <>

#include <stdio.h>


The library provides support for the decompilation, fileinfo, and test services. For a more detailed list, see the status page in the documentation.



The recommended way of installing is from Python Package Index (PyPI) with pip:

$ pip install retdec-python

This will install the latest stable version, including all dependencies. You can also install the latest development version directly from GitHub:

$ pip install git+
