Low obfuscation includes:
• Code minification - Removes all unnecessary characters, comments and whitespace
• String encryption - Converts strings into encoded format using base64 and URI encoding
• Domain binding (optional) - Simple check to ensure code runs only on specified domain
Best suited for:
Public scripts where code readability is not critical but some basic protection is needed.
Performance impact:
Minimal (less than 5% overhead)
Medium obfuscation includes:
• All Low level features
• Variable name obfuscation - Replaces all variable and function names with random identifiers
• Number encryption - Converts numbers into mathematical expressions
• Code wrapping - Wraps code in Immediately Invoked Function Expression (IIFE)
• Enhanced domain check - More complex domain validation
Best suited for:
Commercial scripts where balance between protection and performance is important.
Performance impact:
Moderate (10-20% overhead)
High obfuscation includes:
• All Medium level features
• Dead code injection - Adds random code blocks to confuse deobfuscation tools
• Multiple code wrapping - Creates multiple nested function layers
• Checksum validation - Adds runtime integrity checks
• Advanced domain protection - Multiple domain validation methods
• Control flow flattening - Transforms code structure to hide execution logic
Best suited for:
Premium/paid scripts requiring maximum protection.
Performance impact:
Significant (30-50% overhead)
Why Obfuscate Your Code?
JavaScript code is sent to the client's browser, meaning anyone can view your source logic. Obfuscation makes your code difficult to read and reverse-engineer, protecting your intellectual property and algorithms. Our tool runs locally in your browser, so your code never leaves your computer.
How to Obfuscate JavaScript Code
- Input Code: Paste your original JavaScript source code into the text area.
- Select Settings: Choose the desired protection level (Low, Medium, or High) and add a domain lock if needed.
- Get Result: Click 'Obfuscate Code' to generate the protected version, then click 'Copy' to use it.
Frequently Asked Questions
Can obfuscated code be reversed?
While no client-side code is 100% unbreakable, high-level obfuscation makes reverse engineering extremely difficult, time-consuming, and expensive for attackers.
Will this slow down my website?
It depends on the level. 'Low' has almost no impact. 'High' adds complex logic checks which may slightly increase execution time, so we recommend it for core logic rather than UI animations.
