strings target.exe | grep -i "def " (Advanced) For executables that are not Python-based (compiled from C/C++), full decompilation to Python is impossible. However, reverse engineering tools like Ghidra can disassemble the binary to assembly/C. You would have to manually rewrite the logic into Python—a massive undertaking. Part 4: Step-by-Step Guide – Recovering Python Source from an EXE Let’s assume the EXE was created with PyInstaller (the most common case). Step 1: Identify the packer Run the EXE through a detection tool like Detect It Easy or PEiD . If you see "PyInstaller" or "PyExe," proceed. Step 2: Unpack with pyinstxtractor Download pyinstxtractor.py from its official GitHub repository. Run:
pycdc extracted_file.pyc (Linux/Windows tool) Not a decompiler, but you can run the strings command on the EXE to extract any plaintext strings embedded in the binary, including error messages, hardcoded paths, or even snippets of source code. convert exe to py
uncompyle6 extracted_file.pyc > recovered_source.py (Python Bytecode Decompiler) A modern alternative that supports newer Python versions (3.10+ in many cases). It often produces more accurate results than uncompyle6. strings target
In the world of binary analysis, patience and the right toolchain are worth more than any mythical "EXE to PY converter." Do you have a specific EXE you’re trying to recover? Share your situation in the comments below—but remember to respect intellectual property and software licenses. Part 4: Step-by-Step Guide – Recovering Python Source
The short answer is: But the long answer is far more interesting. Under specific conditions, you can recover Python code from an executable—or at least extract valuable information from it.
works for Python 2.7–3.8. decompyle3 works for Python 3.7–3.9+.
python pyinstxtractor.py myapp.exe If successful, you’ll see an output folder like myapp.exe_extracted . Inside the extracted folder, look for a file without an extension or named similar to the original script (e.g., myapp or main ). That’s likely the entry point bytecode. Step 4: Decompile the bytecode Using uncompyle6 or pycdc :
