JavaScript DeObfuscator

Identify the vulnerabilities in your JavaScript code, debug and fix your code

About JavaScript DeObfuscator Tool

The term "obfuscation" comes from the Latin word "obscūrus," which means "darkened." The original meaning of the word was to conceal or hide something in a dark place. In computer science, it has come to mean confusing programming language code by using techniques such as variable names with unusual spellings, introducing deliberate errors, and using uncommon or unnecessary features of a programming language.

JavaScript is one of the languages ​​that have contributed to this development. The evidence for this is that most applications of all kinds and variations are based on JavaScript.

Javascript DeObfuscator by is a tool that can help you to identify the obfuscation of your javascript code. It is a very useful tool for understanding how your code has been obfuscated, and deobfuscate it to make it readable again.

The Javascript DeObfuscator has been developed to help developers who are trying to find vulnerabilities in web applications or websites.

This tool is a really helpful tool for those who need to debug and fix their code. It helps them find out the cause of the issue faster than traditional methods like debugging, tracing, and profiling.

Use this tool JavaScript Obfuscator to obfuscate your JS code.

How to use TopOnlineTools JavaScript Deobfuscator?

The TopOnlineTools JavaScript Deobfuscator is very easy and simple to use, all you have to do is to copy and paste your code inside the toolbox, click Deobfuscate and let the tool do the rest. Here's how you can use this tool:

  1. Copy your Obfuscated JavaScript code from your JS file.
  2. Go to
  3. Paste your Obfuscated JS code inside the toolbox.
  4. Click Deobfuscate. Once you do that, the tool will immediately Deobfuscate the Obfuscated JS code and give you a clean, readable, and nice-looking JavaScript code.
  5. Copy the Deobfuscated code manually or use the copy icon in the top left of the toolbox.

Why Use Our JavaScript Deobfuscator tool?

There are some reasons why you may want to use a JavaScript Deobfuscator tool, some of them are:

  1. Using the JavaScript Deobfuscator tool will make things go faster. You can deobfuscate your code manually if you have the knowledge to do that, but it's easier to use such a tool. Programmers usually use auxiliary tools to remove the opacity and do not do it manually to save time.
  2. JavaScript Deobfuscator tools are more accurate and effective. Yes, you can do code deobfuscating by yourself, but in the end, you are a human, and you can make mistakes. Using such tools will leave no option for mistakes.
  3. The JavaScript Deobfuscator does not make a simple modification or just rearrange the codes, but rather understands and corrects them as it simplifies the expression of the codes It also differentiates between the combination and summation operations and applies them automatically to the codes. So, it does the job better than humans.

What is JavaScript?

JavaScript is a high-level programming language that was originally introduced by Netscape in 1995. It is now one of the most popular programming languages in the world. It allows developers to create interactive web pages and other content for the Internet. It can also be used to create applications for mobile phones and desktop computers.

JavaScript is used by programmers to make their websites interactive, dynamic, and more interesting for the user, and it has become one of the most popular programming languages in the world.

What is JavaScript Deobfuscator?

JavaScript Deobfuscator or Unobfuscator is a tool that can help you to get rid of obfuscation and minification in JavaScript. It's used in the process to recode the JavaScript obfuscated codes to retrieve them to the original codes and make them clear and understandable.

It is an online software that removes the obfuscation from JavaScript files. It does not change the functionality of the code, it just makes it readable for humans.

JavaScript Deobfuscation is an important step in the development, software development, and security of the applications. And this tool can help you to debug, understand the code, and fix bugs.

What is Deobfuscation?

Deobfuscation is the process of removing obfuscation from a program. It can also refer to the process of reversing engineering software. It is a technique that reverses the obfuscation in order to make it more human-readable and understandable.

In general, to deobfuscate something means to make it more clear and more understandable. De-obfuscation is recoding the obfuscated code to retrieve the original code which is the process of transforming the data from one shape (obfuscated code) to another one to get the original information or data and make it easier to understand.

How does JavaScript Deobfuscator work?

JavaScript deobfuscator makes the data clear which makes you understand how the code looks and how it works. Virtually it makes a removal Protection layer by rewriting or correcting codes.

Some of the deobfuscators are specific to programming languages and others are for general use that has no specific language but it's somehow difficult to use. And some of them just break the codes into pieces regardless of their understanding of how they work, and this is one of the simplest ways.

But JavaScript deobfuscator understands the codes and the way they work, and this is done in precise steps in which the codes are rearranged and read and the commands are understood.

To understand these codes, they contain arrays. These arrays rearrange and simplify commands, and combine or sum, according to what the codes need, and because all of this is defined in their arrays.

This process is similar to re-breaking Puzzles and re-installing them in their original form by placing each part in its designated place with an understanding of its role and method of work, and you may do it manually or with tools.

How do I Deobfuscate my JavaScript code?

The JavaScript deobfuscation can be done manually without using any tools or by using the TopOnlineTools JavaSript Deobfuscator tool, it will deobfuscate the JavaScript code automatically.

Using TopOnlineTools JavaScript Deobfuscator is one of the best solutions to deobfuscate your JavaScript code. All you have to do is to paste your code into the toolbox above and click "deobfuscate ". It will read, understand what it needs and deobfuscate and give it to you in the native JavaScript obfuscated codes.

What are the benefits of using the JavaScript Deobfuscator tool?

The JavaScript Deobfuscator tool has many benefits some of which are listed below.

  • The first and primary benefit, and perhaps the main purpose of making it is to save time and facilitate the process of deobfuscation.
  • This tool is beside what we mentioned previously in its ease, but it is also powerful.
  • The arrays also contain letters (numbers, strings, null, etc) that simplify complex matrices This is done by converting long orders into more comprehensive, sounder, and clearer orders perfectly.
  • It renames and defines undefined matrices and converts complex ones to Easy static numbers, and evaluates the functions as we said earlier.
  • Some developers also use it to verify and check the codes, review them and find weaknesses in them, as this makes the codes more powerful and reduces the percentage of error in them, making them difficult to hack.
  • It can also be used to restructure or re-engineer codes so that the developer cannot hide the way of engineering the codes and the way they are built, you can easily read the data of the array and its codes.
