|Compact Code||Removes line breaks from the output obfuscated code.|
|Identifier Names Generator||
Use this option to control how identifiers (variable names, functions names, etc) will be obfuscated.dictionary
Generates identifier names using names from
Generates random identifier names using a hexadecimal pattern (e.g:
Uses short identifier names (e.g:
This options sets identifiers list for
This options makes all global identifiers have a specific prefix.
Use this option when obfuscating multiple files that are loaded on the same page. This option helps to avoid conflicts between global identifiers of these files. Use a different prefix for each file.
Enables the obfuscation of global variables and function names with declaration.
requires the Compact Code setting.
|Control Flow Flattening||
Enables code control flow flattening. Control flow flattening is a structure transformation of the source code that hinders program comprehension.
|Dead Code Injection||
This feature adds random blocks of dead code (i.e: code that won't be executed) to the obfuscated output, making it harder to be reverserd-engineered.
requires the String Array option.
This feature splits literal strings into chunks with length of the
Removes string literals and place them in a special array. For instance the string "Hello

|Transform Object Keys||
Transforms (obfuscates) object keys.
For instance, this code
ideally used with the String Array setting.
|Escape Unicode Sequence||
Converts all the strings to their unicode representation. For instance, the string
This convertion is pretty easy to revert, and will increase the obfuscated code size greatly. It's not recommended on larger code bases.
|Disable Console Output||
Disables the use of
This option makes it almost impossible to use the Console tab of the Developer Tools (both on Google Chrome and Mozilla Firefox).
Locks the obfuscated source code so it only runs on specific domains and/or sub-domains. This makes really hard for someone just copy and paste your source code and run elsewhere.Multiple domains and sub-domains
It's possible to lock your code to more than one domain or sub-domain. For instance, to lock

Source maps can be useful to help you debug your obfuscated Java Script source code. If you want or need to debug in production, you can upload the separate source map file to a secret location and then point your browser there. Read more about source maps on the Google Chrome Developer Tools website.Inline Source Map
This embeds the source map of your source in the result of the obfuscated code. Useful if you just want to debug locally on your machine.Separate Source Map
This generates a separate file with the source map. Useful to debug code in production, as this enables you to upload the source map to a secret location on your server and then point your browser to use it.
Use the Source Map Base URL and Source Map File Name to
For instance, if you set the Base URL to
By default (
You can set the target environment of the obfuscated code to one of the following:
