About Us – PyObfuscator | Free Python Code Protection Tool

Our Mission

Python's readability is its greatest strength — and its biggest security weakness. When you distribute a Python script, you distribute your source code. Whether you're protecting proprietary algorithms, license-check logic, API integrations, or automation scripts, pyobfuscator.com gives you an easy first line of defense.

Our mission is simple: give every developer access to professional-grade Python obfuscation for free, with no strings attached and no data leaving their browser.

🔒 Privacy-first: All obfuscation runs entirely in your browser. We never see your code. Zero server-side processing. Zero data retention.

What We Offer

pyobfuscator.com provides a multi-layer Python obfuscation pipeline built entirely in browser-side JavaScript. Unlike server-side tools, your code is processed locally — it never leaves your machine.

How it works:

Your source code is zlib-compressed using Python's deflate-raw algorithm
The compressed binary is Base64-encoded into a safe ASCII string
The encoded string is reversed ([::-1]) to defeat naive base64 scanners
A two-line lambda loader handles decompression and execution at runtime
Optional multi-layer mode applies the full pipeline twice
Optional comment, docstring, and blank-line stripping before encoding

Who Uses This Tool?

Our users range from indie developers distributing CLI tools, to data scientists sharing automation scripts, to agencies delivering proprietary Python packages to clients. If you've ever typed python script.py and worried someone might read it — this tool is for you.

Honest About Limitations

We believe in transparency. Python's dynamic, interpreted nature means no obfuscation is fully irreversible. A determined expert can deobfuscate any Python code given enough time. Our tool raises the bar significantly, but for maximum IP protection, consider combining obfuscation with Cython compilation, PyInstaller packaging, or a proper licensing server.
