Online Javascript Obfuscator


This javascript obfuscator is intended to be used as a resource to convert human readable javascript to a more shrouded code. This serves two purposes:



How it Works

Generally the code from the fist textarea is copied into the second one. In between that here are numerous functions that each are triggered by the options/check boxes. So if none of the checkboxes are on, there will be no change in the code.

Note : If you get errors with the output code, it may be because your source does not have semicolons (;) terminating each line.

Please report any bugs, fixes or suggestions to help make this tool better and remember, always keep the original code!

Remove Line Breaks

Loop through all lines in the text area. Looking at each line one-by-one, if a line has no semicolon at the end, add one and then join it to the line previous

Remove Comments

Loop through all lines in the text area. Looking at each line one-by-one, trim all white space from the line. Then check the fist and second characters in the line. If they are both forward slashes i.e. / , then remove that line.

Good But Not Best...........

Absolutely sucks. De-obfuscated in seconds, literally: just run : for(var i in window) { console.log(window[i]); } or alert();

The filesize of my js has been greatly reduced, but I can't use this on scripts that incorporate dynamic PHP content. My php variables get obfuscated too. Any suggestions?

A waste of time. Too easy to decode the obfuscated code. Simply replace eval by alert, document.write or something similar.
