Obfuscate Your Python Code Instantly
Protect your Python source code from reverse engineering. Rename identifiers, encrypt strings, add junk code, and encode to bytecode — all in your browser.
Powerful Python Protection, Zero Effort
Everything you need to shield your Python source code from prying eyes.
zlib Compression
Your source code is compressed with zlib before encoding, shrinking the payload and adding a binary layer that is invisible to plain-text scanners.
Base64 Encoding
The compressed binary is Base64-encoded into a pure ASCII string — no special characters, safe to embed anywhere, and opaque to static analysis.
Reversed Payload
The encoded string is reversed ([::-1]) before storage, defeating naive base64 decoders and adding an extra layer of confusion.
One-Liner Loader
A single compact lambda — _ = lambda __ : ... — handles decoding and execution. No imports at the top level, no readable structure.
Comment & Docstring Removal
All # comments and triple-quoted docstrings are stripped before encoding, removing developer hints and reducing payload size.
Multi-Layer Wrapping
Optionally apply the zlib+base64+reverse pipeline multiple times, wrapping the loader inside itself for exponentially harder deobfuscation.
Three Steps to Protected Python
Paste Your Python Code
Copy your .py script into the input editor. Works with Python 3 code including classes, functions, comprehensions, decorators, and f-strings.
Configure Protection Options
Optionally strip comments, docstrings, and blank lines before encoding. Enable multi-layer wrapping to apply the pipeline twice for stronger protection.
Download & Deploy
Click "Obfuscate Now", then copy or download your protected .py file. Run it with python obfuscated.py — it behaves identically to the original.
Frequently Asked Questions
Does the obfuscated Python code still run correctly?
.py file. The two-line loader decompresses and executes your original code at runtime using only Python's built-in zlib and base64 modules — no third-party packages needed.What exact format does the output use?
# Python obfuscation by pyobfuscator.com_ = lambda __ : __import__('zlib').decompress(__import__('base64').b64decode(__[::-1]));exec((_)(b'PAYLOAD'))
Where
PAYLOAD is your source code zlib-compressed → base64-encoded → reversed. The lambda and exec share a single line separated by ;. The multi-layer option applies this pipeline twice.
Why is the base64 string reversed?
[::-1]) defeats naive base64 decoders and automated scanners that look for recognizable base64 patterns. The loader reverses it back at runtime before decoding.Can obfuscated Python be deobfuscated?
import zlib, base64; print(zlib.decompress(base64.b64decode(payload[::-1])).decode()). Obfuscation raises the bar against casual inspection and automated tools — it is not encryption. For stronger IP protection, combine with Cython compilation or PyInstaller.Does this work with Python 2?
