🔒 JavaScript Obfuscator – Features and Recommendations

Below is a description of each available feature in your obfuscator tool, along with the benefits and usage recommendations for maximum code protection.

Back

ðŸŒą Seed

Description: A numeric value used to initialize the obfuscation process, ensuring reproducible results.
Benefit: Same seed produces identical obfuscation output, useful for debugging and version control.
Recommended: ✅ Use when you need consistent obfuscation across builds

Tip: Change the seed value for different versions to create unique obfuscated outputs.

⚙ïļ Preset Configuration

Description: Predefined obfuscation profiles for different use cases.
Options:

  • Low Protection: Basic obfuscation with minimal performance impact
  • Medium Protection: Balanced obfuscation with moderate performance impact
  • High Protection: Maximum obfuscation with significant performance impact
  • Custom: Manually configure all settings
Benefit: Quick setup for common use cases without manual configuration.
Recommended: ⚠ïļ Start with Medium preset and adjust as needed

ðŸŽŊ Target Environment

Description: Specifies the JavaScript environment your code will run in.
Options:

  • Browser: Optimized for web browsers
  • Browser (no eval): More discreet and efficient
  • Node.js: Optimized for server-side execution
Benefit: Environment-specific optimizations and compatibility checks.
Recommended: ✅ Match to your actual runtime environment

✅ Compact Code

Description: Removes unnecessary whitespaces, line breaks, and comments.
Benefit: Reduces file size and makes code harder to read.
Recommended: ✅ Always

ðŸ›Ą Self-Defending

Description: Adds protections that make the code break or behave incorrectly when beautified or debugged.
Benefit: Makes reverse-engineering more difficult.
Recommended: ⚠ïļ Use only for production (may affect performance)

ðŸšŦ Disable Console Output

Description: Blocks console.log, console.error, and other console methods.
Benefit: Prevents revealing internal logic or debug info.
Recommended: ✅ Recommended for production

🔁 Control Flow Flattening

Description: Transforms the logic structure (like if, while, etc.) into a confusing switch + loop combo.
Benefit: Makes logic very hard to follow.
Recommended: ⚠ïļ High protection, but can increase size and slow down code

ðŸ§Đ String Array

Description: Moves all string values to a single array and replaces them with array lookups.
Benefit: Hides visible text and strings in the code.
Recommended: ✅ Highly recommended

🔄 Rotate String Array

Description: Rotates the string array so the order of strings is shuffled.
Benefit: Obscures the original sequence further.
Recommended: ✅ Combine with String Array

🔀 Shuffle String Array

Description: Randomizes the index order of the string array and adjusts references accordingly.
Benefit: Increases resistance against pattern analysis.
Recommended: ✅ Combine with Rotate

🔄 String Array Calls Transform

Description: Transforms calls to the string array, making the access pattern more complex.
Benefit: Adds another layer of obfuscation to string array access patterns.
Recommended: ✅ When using String Array for stronger protection

Tip: Works best with String Array Threshold set to 0.5 or higher.

ðŸ“Ķ String Array Wrappers

Description: Wraps string array accesses in additional functions or variables.
Options:

  • Count: Number of wrapper layers (1-5)
  • Type: Variable or Function wrappers
  • Parameters Max Count: Maximum parameters for function wrappers
Benefit: Makes string array access patterns much harder to analyze.
Recommended: ⚠ïļ 2-3 wrappers for balance between protection and performance

🔗 String Array Index Shift

Description: Shifts the indexes when accessing the string array by a fixed value.

Benefit: Adds another layer of obfuscation to string references, making pattern recognition harder.

Recommended: ✅ Always enable when using String Array for better protection

Tip: This works best when combined with String Array encoding and rotation.

ðŸ”Ē String Array Indexes Type

Description: Controls how indexes are generated when accessing the string array.

Options:

  • Hexadecimal Numbers: 0x1a3f (numeric)
  • Hexadecimal Strings: "0x1a3f" or "1a3f" (as strings)
  • Both: Randomly alternates between both formats
Benefit: Makes pattern analysis harder by breaking type consistency.

Recommended: ✅ Mixed for strongest obfuscation

Tip: Combine with String Array Encoding to hide the actual hex values.

✂ïļ Split Strings Chunk Length

Description: Controls how long each chunk should be when splitting strings.
Benefit: Allows fine-tuning of string splitting obfuscation.
Recommended: ⚠ïļ 5-15 for optimal balance (lower = more obfuscation but larger code)

🔐 Encoding (Base64 / RC4)

Description: Encodes the string array with Base64, RC4, or both.
Benefit: Prevents easy extraction or reading of strings.
Recommended: ✅ For high-security needs

✂ïļ Split Strings

Description: Breaks long strings into smaller chunks and reassembles at runtime.
Benefit: Prevents full string detection and matching.
Recommended: ✅ Useful for sensitive data

ðŸ§ą Transform Object Keys

Description: Converts readable keys like obj.name to obj['aX1'].
Benefit: Hides the purpose and meaning of object properties.
Recommended: ✅ Optional, increases complexity

ðŸŠĶ Dead Code Injection

Description: Inserts non-functional (unused) code into the final bundle.
Benefit: Misleads attackers and increases obfuscation depth.
Recommended: ⚠ïļ Use selectively, may increase size significantly

ðŸ”Ē Numbers to Expressions

Description: Converts numbers to equivalent math expressions (e.g., 5 → 2+3).
Benefit: Obscures simple numeric values.
Recommended: ✅ Use for extra confusion

ðŸ§Ū Simplify Expressions

Description: Modifies expressions to use alternative logic.
Benefit: Breaks pattern recognition and makes analysis harder.
Recommended: ⚠ïļ Optional, minor benefit

🔠 Identifier Names Generator

Description: Controls how variable and function names are transformed during obfuscation.

  • Hexadecimal: Generates names like _0x28ba3 (default)
  • Mangled: Generates short names like a, b, c
  • Mangled Shuffled: Short names in random order for extra confusion

Benefit: Makes code analysis significantly harder by removing meaningful identifiers.

Recommended: ✅ Hexadecimal for balance, Mangled Shuffled for maximum obfuscation

⇄ String Array Index Shift

Description: Shifts the indexes when accessing the string array by a fixed value.

Benefit: Adds another layer of obfuscation to string references, making pattern recognition harder.

Recommended: ✅ Always enable when using String Array for better protection

Tip: This works best when combined with String Array encoding and rotation.

ðŸ”Ģ Unicode Escape Sequence

Description: Converts characters to Unicode escapes (e.g., a → \u0061).
Benefit: Prevents clear-text visibility in the source.
Recommended: ✅ For hiding string content

ðŸŽĻ CSS Protection PREMIUM

Description: Embeds and obfuscates CSS within JavaScript, applying multiple layers of protection.
Benefit: Prevents easy extraction of your styles and design.
Recommended: ✅ For protecting proprietary UI designs

Tip: Combine with String Array encoding for maximum CSS protection.

🌐 Domain Lock PREMIUM

Description: Restricts code execution to specific domains you specify.
Benefit: Prevents unauthorized use on other websites.
Recommended: ✅ Essential for licensed code distribution

Tip: You can specify multiple allowed domains (comma-separated).

⏰ Expiration Date PREMIUM

Description: Makes the code stop working after a specified date.
Benefit: Ideal for trial versions or time-limited licenses.
Recommended: ✅ For demo versions and temporary access

Tip: Combine with Domain Lock for comprehensive license control.
