Unable to read .pyc bytecode files directly? This tool parses .pyc files (a binary format containing Python bytecode) generated by Python compilation and restores them into readable .py source code. Since .pyc files are the bytecode format executed by the Python interpreter, this tool uses reverse engineering to convert them into a structure closely resembling the original code, outputting a Python script that can be directly analyzed.
Why are there no original comments after decompiling?
Bytecode does not contain comment information. Decompilation can only restore the logical structure of the code.
Is the new Python 3.12 version supported?
Currently, we support up to Python 3.11. Support for newer versions will be available once the bytecode parsing library is updated.
The maximum file size is 10MB. The decompiled result may lose variable naming details. Please do not use this tool to crack copyright-protected code. When handling abnormal files, we recommend checking the integrity of the bytecode header information.
We recommend using this tool in conjunction with source code version control records. When only a .pyc file is available, you can verify the accuracy of the restoration using a code comparison tool (like diff) after decompiling. Typical example: A module.pyc file compiled with Python 3.8 can be processed to recover a module.py file containing import statements and function definitions, though the original docstrings may be lost.
