UnPYC

Overview

Important: I won't push more updates to this tool, since it was merely a hobby + learning project.

This is a GUI tool for decompiling Python bytecode .pyc/.pyo back to .py using existing tools.

It's also bundled with a modified pyinstxtractor for making it easy to extract pyinstaller packaged executables.

Features

Can decompile Python bytecode versions 2.6, 2.7, 3.1, 3.2, 3.3, 3.4, 3.5, 3.6, 3.7, 3.8, using tools like uncompyle6.
Can extract pyinstaller package using pyinstxtractor.
Makes it easy to decompile pyc's even without Python installed in the system.
Helps in decompiling pyc's of different versions.
Works offline if dependencies and Python sources are satisfied, which can be done easily.

How to use

Currently, it's Windows only. Download the latest release here, unzip it and open the UnPYC.exe in the folder. The GUI is very straightforward. For most users, this will be the way to do stuff.

This is an example of extracting a pyinstaller packaged .exe and decompiling the bytecode stored in it.

You can change the theme from the settings menu.

Portable Python

This project uses portable Python distributions from here.

To do

There's a lot of stuff to do in this, like

~~Adding preinstalled Python decompiling~~
Using bundled Python for decompiling
Lots (and I mean lots) of code refactoring
Adding Linux support
Adding more decompiling tools support
Adding Python 3.9, 3.10
Adding macOS support
Add Linux release
More user friendly UI
~~Cleanup after usage~~ Added a clean button in settings

This project is under development, so there might be tons of bugs and crashes. Also, the console isn't hidden right now, so that errors can be seen there.
