JavaScript Obfuscator Online
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
