Convert Exe | To Py

Let’s assume the EXE was created with PyInstaller (the most common case).

The most reliable open-source decompiler for older Python versions (3.8 and below).

Separating the embedded .pyc (bytecode) files from the .exe wrapper.

(C++ Python Bytecode Disassembler): A powerful alternative for newer versions of Python where other decompilers might fail. Step-by-Step Process convert exe to py

If you are working on a specific file and ran into issues during extraction, let me know: What are showing up in your terminal? Which Python version was used to build the file? Do you know if the file was obfuscated ?

PyInstaller is the most common tool for packaging Python scripts into EXEs. The pyinstxtractor.py script can unpack a PyInstaller-generated EXE.

You are now ready for the final transformation. Let’s assume the EXE was created with PyInstaller

For → Always keep backups next time (Git + cloud backup).

: This guide applies strictly to packaged Python scripts (PyInstaller, py2exe, cx_Freeze). If the developer compiled the Python code into hard native machine code using tools like Cython or Nuitka, extraction via pyinstxtractor is impossible. Recovering that code requires advanced assembly debuggers like IDA Pro or Ghidra.

Open your system Command Prompt (or Terminal) and navigate to your working directory. Run the extraction script against your file: python pyinstxtractor.py my_application.exe Use code with caution. Step 3: Analyze the Output Do you know if the file was obfuscated

Now, you're ready to start your own project. Choose the right tool for the job and happy extracting!

Practically identical to Uncompyle6 but with better support for Python 3.8 features like walrus operators ( := ).

for file in *.pyc; do uncompyle6 $file > $file%.pyc.py; done
