Obfuscate JavaScript

Make JavaScript harder to read, then test the transformed output

Note: Obfuscation can make code harder to read, but it is not a security boundary. Do not rely on it as the only protection.

Input + outputTransform JavaScript and verify the result in your environment

Online Obfuscate JavaScript Tool

This tool transforms JavaScript into a harder-to-read form. Obfuscation is not encryption or access control, and code that depends on reflection, dynamic property names, or evaluated source may need extra testing.

How to Use This Tool

Paste your original JavaScript into the input editor.
Click Obfuscate to generate the transformed output.
Copy the result and use it in your workflow.

Why Obfuscate?

Make code harder to read or reverse-engineer.
Discourage casual copying of client-side logic.
Produce output designed to preserve behavior, then test it in the real runtime.

Obfuscate and Encrypt

Obfuscate your JavaScript with this tool.
Copy the obfuscated output to your clipboard.
Use the Encrypt Tool if you need to encrypt the output for storage.

FAQ

Does this tool change how my code runs?

It can. The transformer is designed to preserve behavior, but reflection, dynamic code, source inspection, and environment assumptions can break. Test the output before release.

Is my code stored?

Obfuscation changes how code is presented; it does not protect secrets or replace access controls.
