How to use JS Obfuscator
- Paste JavaScript or upload the file you want to obfuscate.
- Choose a protection level that matches the risk of breakage you can tolerate.
- Generate the output, then test the resulting script in the real page before publishing.
Why use JS Obfuscator
JavaScript obfuscation is useful when you want to discourage casual copying of browser code, small game logic, widget behavior, or public demo scripts. It changes how the code looks, not what the browser is allowed to access.
Because the browser still receives and runs the script, obfuscation is not a secure place for secrets. Treat it as a practical friction layer and keep private operations on the server. Stronger settings can also make debugging harder, so test carefully.
Best for JS Obfuscator
- Protecting public widget logic from casual reuse.
- Shipping demos where readable source is not needed.
- Adding friction before distributing a front-end script.
Practical notes
- Keep the original source in your project.
- Avoid hiding API keys or credentials in client-side code.
- Test old browsers separately if your audience still uses them.
