Use a decompiler like uncompyle6 or decompyle3 :
If you must proceed, respect intellectual property and use these techniques only on your own code or with explicit permission. # Extract PyInstaller EXE python pyinstxtractor.py target.exe Decompile single .pyc uncompyle6 file.pyc > file.py Decompile all .pyc in folder for f in *.pyc; do uncompyle6 $f > $f%.pyc.py; done Scan EXE for Python strings strings target.exe | grep -E "import |def |class " Check if EXE is PyInstaller strings target.exe | grep "PyInstaller" This guide is for educational purposes. Always ensure you have the legal right to reverse engineer any executable. convert exe to py
The short answer is: But the longer answer is more nuanced. While you cannot get the original source code with comments and variable names, you can often recover a large portion of the logic, reconstruct Python bytecode, and sometimes even retrieve the original .py files – depending on the tool used to create the EXE. Use a decompiler like uncompyle6 or decompyle3 :
def greet(name): # This comment will be lost return f"Hello, name!" print(greet("World")) The short answer is: But the longer answer is more nuanced
