Javascript Obfuscator

Prevent people from stealing your codes and work using an efficient JavaScript obfuscator, tap to know more!

You can prevent people from stealing your codes and work using an efficient JavaScript obfuscator. It is a tool that transforms the script or codes into a different representation that is more complex than the original one. In other words, the transformed JavaScript is challenging to understand and reuse without authorization because of its complexity. The primary purpose of JavaScript obfuscator is to secure the content from wrong reach.

JavaScript Obfuscator

The Obfuscation doesn’t mean any change in the functionality or results of your work as the JavaScript obfuscator only modifies the representation of the script. It is more or less like the other similar tools including Closure Compiler and UglifyJS. The only difference is that the data modified by UglifyJS can be modified into a readable format using beautifiers but in the case of JavaScript obfuscator, there is no such gateway.

Working Of JavaScript Obfuscator

The JavaScript obfuscator works on the transformation that takes place on variables, renaming, functions, string exclusion, and more. The source code or script is transformed or molded into something non-understandable or unreadable without impacting its functioning or working. The JavaScript obfuscator changes the JavaScript source coding to prevent it from the reach of thieves or attackers ensuring 100 % safety. JS obfuscation is concealing of script, coding, or data, but that doesn’t mean alteration of your work. To simplify this, it is said that the strong JS obfuscation is the one that will not modify the layout or control flow of the webpage. It only used the optimization to target the following identifiers, numbers, Booleans, predicates, functions, statements, and regular expressions. The common JS obfuscation methods include the splitting of the script, encoding, renaming, reordering, and other concealing methods. An in-depth understanding of each of these techniques is important and as per my thinking, their names are quite self-explanatory. For example, reordering means a change of order of elements, renaming is a modification of names, and so forth. While the control-flow JS obfuscation requires detail because of its more comprehensive application, the control-flow JS obfuscation aims to make the flow complex to follow by eliminating the natural constructs or codes which are easier to understand. Technically, it splits the source coding or scripts like loops, body, and branches and put them all in a switched form where they can control the flow but are not easily readable for the reader (attacker). The JS obfuscation also includes clones: basic copies and dummy copies, where basic copies are blocks that can function interchangeably. In contrast, the dead clones are dummy versions of basic ones that are never functional. The combination of techniques adds more complexity and intricacy for the stealer as it makes the overall understanding difficult. Then comes another approach to JS obfuscation called polymorphism. Morpho is the term that reflects structure, and polymorphic JS obfuscation is a technique that creates a new coding and ensures to change of the old one completely. This unique method is super reliable in terms of security.

Perks Of Obfuscation

Obfuscation brings the list of perks, but its main advantage and purpose are limited to making the content or working securely from the hands of stealers or attackers. Intentionally or unintentionally, the obfuscation makes the JavaScript files compact and minimal by reducing their size. This helps in the overall usability as handling small-sized files is easier and more efficient; also, it requires less time for loading and overall functioning. Secondly, the JavaScript obfuscator provides endless protection ensuring that the data is hundred-percent safe. Unlike other obfuscators, there is no gateway or tool to modify the data of JavaScript and make it readable so it's protected. Also, the locking is quite powerful, and the entire coding is based on the personal IP address and domain, making stealing impossible for hackers or attackers. The best part of using the JavaScript obfuscator is that it will not cause any negative impact on the quality or other elements of your work. In other words, the JavaScript obfuscator makes sure to preserve the operational quality of the script so that you will not face any obstacles. This is crucial because none of us wants to lose the quality content or script we produced. Last but not the least, I am in love with the user interface of the JavaScript obfuscator. This is not just the word of mouth as the graphical user interface, shortly called GUI, uses icons, windows, menus, and other smart options that help you reach different places within the browser. Also, it commands on the keyboard shortcuts that save half of your time and make you reach the places instantly. That's all for obfuscation, and to make you understand better let's enrolled into a conversation about JS:

JavaScript - An In-Depth Review

JavaScript is a user-friendly and lightweight programming language that is based on objects. It is adopted by various websites to script and generate their web pages. All in all, JavaScript is a full fledge language that interprets and enables user interactivity on the website using an HTML-based document. JavaScript programming language was initially developed in 1995 to add different programs and contents to the webpage of Netscape Navigator web browser. With time, JavaScript started using different graphical browsing sites and the language become the best for its non-loading page interaction. In other words, users can open different links or columns on the webpage programmed by JavaScript without loading. In a nutshell, the simplicity, straightforward interface, and interactivity are the reasons behind the increased demand for JavaScript. For your information, Java and JavaScript are two different things and there is no connectivity between them. The name JavaScript was adopted from Java (a programming language) because of its popularity and well-repute in the market. In a word, JavaScript is used by web browsers and databases like Mongo-DB and Counch-DB as a scripting language.

Features of JavaScript

All the top-end web browsers are in support JavaScript because it does not need a separate execution environment. JavaScript has followed or adopted the structure and interface of the C programming language. It is weakly typed, which also depends on the operation and demand. In addition, JavaScript is an object-based language that does not use groups but prototypes. In a few words, JavaScript is case-sensitive, interpreted, lightweight, user-friendly, and highly supportive. It means it works well with the windows operating system, Mac operating system, and more. The best thing about JavaScript is that it provides better control and accessibility to users over web browsing platforms.

Applications Of JavaScript

Client Side & Server Side Validation

Validation is the checking of data you entered. For example, whether the formatting is right for the application or not. If the validation or checkup is done on the premises of the web browser it is called client-side validation while the validation on the server level is considered server-side validation.

Dynamic Drop-down Menus

JavaScript creates dynamic drop-down menus which are extremely beneficial and in demand these days. The drop-down menus save the extra time and effort that you put into scrolling large websites by providing quick access to all the options using a drop-down list. Through the list, you can jump to different options in no time.

Displaying Date and Time

Another application of JavaScript is the display of time and date that saves the user time and effort that he consumes in opening the calendar. This is helpful in educational websites, meteorological web pages, and many other platforms. Also, you can create pop-up windows and dialogue boxes for important announcements related to the organization using JavaScript.

JavaScript Security

Security is the biggest concern when it comes to scripting, likewise, JavaScript provides authors legal authorities that cannot be shared by any other person. To reduce the overall risk, there are different restrictions made within JavaScript like the scripts functioning in the sandbox are limited to performing web-based tasks only. In other words, it cannot change or perform the general-purpose tasks of programming like making documents. Over that, the scripts of one website cannot be used on other websites. This is called the origin policy of JavaScript that aims to secure the usernames and password-related information of users. Also, JavaScript makes sure that cookies are not transferred from one site to the other. JavaScript has different subsets that are designed to provide enormous and reliable security, especially to the personal information and coding by parties. With time, security is overall improving through new projects like closure toolkits that have been embedded for isolation and safety purpose and more. Last but not the least, content security policies are made to ensure the security of codes executed on a particular web browser. Although JavaScript is a secure thing with an array of policies, it does have some problems. So, I decided to highlight a common security-oriented problem of JavaScript for better knowledge and understanding. Let’s begin:

Cross-Site Vulnerabilities

The most common problem with JavaScript security is the cross-site script which is shortly known as XSS. The XSS vulnerabilities usually happened when an attacker or thief reaches the target website, for example, a banking website to derive the data of the victim. The script includes banking applications, personal data of privileges, or other secretive information related transferring and deposition of money. This is called the loss of authorization of the victim in JavaScript. Every problem has a solution; likewise, the XSS vulnerabilities can be solved by using HTML that displaces untrusted data. Some browsing platforms has partial security against attackers as they provide URL that includes a malicious script. The advantage is that the user of those sites is less likely to be vulnerable to attackers. To get rid of security issues, there is nothing better than obfuscation.


How does the obfuscation work?

The obfuscation works on the transformation that takes place on variables, renaming, functions, string exclusion, and more. The source code or script is transformed or molded into something non-understandable or unreadable without impacting its functioning or working. The obfuscator changes the source coding to prevent it from the reach of thieves or attackers ensuring 100 % safety.

Why should I use a JavaScript obfuscator?

JavaScript is a programming language widely used to develop browsers, web pages, and websites because of its excellent GUI, pop-up notifications, drop-down menus, validation, and more. But, the only downside of JS is security because the stealers can view and copy your data and steal personal information. To fill the gap by ensuring 100% protection, the JS obfuscator is used that compact and modify the script and keep it safe.

Is the JavaScript obfuscator project specific?

No, the JavaScript obfuscator is not a restricted tool. It is quite flexible and has a tendency to be used for all kinds and sizes of projects. However, there can be a few limitations for complex webpages, but don’t worry, JS obfuscator is free and wide.


Safety comes first! The JavaScript obfuscator is like a lock on your home’s main entrance that ensures maximum protection and resists thieves or attackers. The JS obfuscator molds the original data or script by changing its ordering, numbers, names, and more and transform it into something unreadable and inaccessible so that your data remains secure. It is widely useful, especially for banking websites, and possesses a lot of perks. Swipe up to read more!
