Javascript Obfuscator 3.0.5.0

Scramble, obfuscate, and pack JavaScript code!

Javascript Obfuscator converts the JavaScript source code into scrambled and completely unreadable form, preventing it from analysing and theft.

Javascript Obfuscator can:

• process javascript tags in html files and all .js files associated with html pages as well as separate .js files
• remove comments and white spaces, reducing the file size and minimizing the loading time
• pack the code as a long line
• add finishing ";" when appropriate
• create a list of function and variable names
• generate new non-understandable names and rename functions and variables depending on user settings
• work with command line

Compare how the same piece of code looks before:

//detect which browser is used
var detect = navigator.userAgent.toLowerCase();
var OS,browser,version,total,thestring;
if (checkIt('konqueror'))
{
browser = "Konqueror";
OS = "Linux";
}
else if (checkIt('opera')) browser = "Opera"
else if (checkIt('msie')) browser = "Internet Explorer"
else if (!checkIt('compatible'))
{
browser = "Netscape Navigator"
version = detect.charAt(8);
}
else browser = "An unknown browser";
//version of browser
if (!version) version = detect.charAt(place + thestring.length);
//client OS
if (!OS)
{
if (checkIt('linux')) OS = "Linux";
else if (checkIt('x11')) OS = "Unix";
else if (checkIt('mac')) OS = "Mac"
else if (checkIt('win')) OS = "Windows"
else OS = "an unknown operating system";
}

//check the string
function checkIt(string)
{
place = detect.indexOf(string) + 1;
thestring = string;
return place;
}

and after processing by Javascript Obfuscator:

var e=navigator.userAgent.toLowerCase();var f,b,c,total,d;if(a('konqueror')){b="Konqueror";f="Linux";};else if(a('opera'))b="Opera";else if(a('msie'))b="Internet Explorer";else if(!a('compatible')){b="Netscape Navigator";c=e.charAt(8);};else b="An unknown browser";if(!c)c=e.charAt(g+d.length);if(!f){if(a('linux'))f="Linux";else if(a('x11'))f="Unix";else if(a('mac'))f="Mac";else if(a('win'))f="Windows";else f="an unknown operating system";};function a(string){g=e.indexOf(string)+1;d=string;return g;};

You can see the difference, can’t you?
