Cleanor Labs
These sections explain the job in plain language and set expectations for what the tool should do well.
This JavaScript obfuscator makes your code harder to read at a glance by renaming local identifiers to hex-style names, encoding string literals as hex escapes or base64 with a runtime decoder, optionally inserting junk code, and stripping whitespace. Everything runs locally in your browser, so your source never leaves your machine. Be honest about what this is: light obfuscation deters casual copying and reverse engineering, but it is not real protection and a determined reader can undo it. Use it to discourage tampering, not to secure secrets.
Short answers for the questions people usually have before trying a utility like this.
No. Obfuscation only makes code harder to read; it can be reversed with a deobfuscator or by hand. Never rely on it to hide passwords, API keys, or other secrets, which should always live on a server.
The transform is conservative: it preserves strings, templates, comments, and regular expressions, and only renames identifiers it can confirm are safe. Always test the output before shipping, especially with reflective code such as eval.
No. All processing happens in your browser using JavaScript. Your code is never sent to a server, so it is safe to obfuscate private or proprietary files.
Every tool on Cleanor is free with no sign-up, no credits, and no limits. Files are processed privately in your browser. Looking for on-device phone cleanup and Premium features? That lives in the Cleanor app.
Rename local variables, encode string literals, add junk code, and strip whitespace to make JavaScript harder to read. This is light obfuscation, not real protection, and it can be reversed.
Processed locally in your browser. Obfuscation deters casual reading only, it does not secure your code.
