JavaScript Obfuscator

Powerful JavaScript Code Protection

Shield your JavaScript from prying eyes and unauthorized copying with our advanced obfuscator. Whether you are protecting proprietary algorithms, licensing logic, or sensitive client-side code, this tool transforms your readable scripts into scrambled versions that execute flawlessly but resist reverse engineering attempts.

Flexible Encoding Levels

Choose the obfuscation strength that fits your needs:

• None - Basic compression that removes whitespace and comments while keeping code structure intact
• Numeric - Applies numeric encoding for moderate protection with smaller output size
• Normal - Standard obfuscation with variable encoding, ideal for most protection needs
• High ASCII - Maximum obfuscation using extended ASCII characters for strongest protection

Advanced Configuration Options

Fine-tune the obfuscation process with additional settings:

• Fast Decode - Include an optimized decoder for faster script execution in browsers
• Special Characters - Encode special characters in variable names for extra obfuscation
• Remove Semicolons - Strip unnecessary semicolons to reduce output size further

Convenient File Handling

Work with your code the way you prefer. Paste code directly into the editor or upload JavaScript files up to 1MB. Once obfuscated, download the protected code as a ready-to-use .js file with a single click.

Real-Time Statistics

Monitor the obfuscation results with detailed statistics showing original and output file sizes, compression percentage, and line count changes. This helps you balance protection level against file size for optimal performance.

Understanding the Protection

Our obfuscator uses the proven Dean Edwards Packer algorithm, trusted by developers worldwide. While obfuscation adds a strong deterrent against casual code theft and makes reverse engineering significantly more difficult, remember that no client-side protection is absolute. For maximum security, combine obfuscation with server-side protection strategies.
