JavaScript Obfuscator

Rewrite JavaScript so it still runs but is much harder to read.

Obfuscation slows people down but is not encryption. Never put passwords or API keys in browser code.

Rewrite JavaScript so it keeps working but becomes difficult to read. Higher levels add more protection and produce larger, slower code.

Features

Three Levels
Balance protection against file size and speed.
String Protection
Text in your code is moved and encoded.
Private
Obfuscation runs in your browser and your code is not uploaded.

Use Cases: When This Tool Helps

  1. Protect client-side logic

    Make it harder for others to copy pricing calculators, games, or quiz logic from your site.

  2. Deliver code to clients before payment

    Share a working demo without handing over readable source code.

  3. Discourage tampering in browser games

    Make it harder to edit scores or rules from the browser console.

  4. Protect licensed widgets and plugins

    Add a layer of difficulty for people trying to remove license checks.

  5. Hide simple API endpoints and keys

    Make casual inspection harder (while keeping real secrets on the server).

  6. Learn about code protection

    See how obfuscation transforms code and why it's not real encryption.

How to Use

  1. Paste your JavaScript.
  2. Choose a protection level.
  3. Press Obfuscate, then test and copy the result.

FAQ

Does this make my code secure?▾

No. It only slows people down. Keep passwords, API keys and private logic on the server.

Will it slow my code down?▾

It can, especially at the high level. Test the result before you publish it.
