What is Base64 to JSON Converter Online Free Tool?

Base64 to JSON converter is an online tool which automatically convert bas64 to JSON format.

Base64 encoded string will be converted into decoded JSON string in a single click.

This tool made in such a way that whatever the input string has been put into an input box, it will start recognizing the format and nature of that string. If the user input is not a valid base64 string then tool will show an error.

This is a very useful feature to identify if the provided encoded text is actually a base64 text or not.

If tool recognizes the correct base64 and JSON format, then you will see the output, if not then you will see the invalid error.

What is base64 and why people use it?

To put it simply, it is an encoding mechanism that converts binary data into a human readable data in the form of sequence of characters.

You can see this chart to know more.


In computer programming, Base64 is a group of binary-to-text encoding schemes that transforms binary data into a sequence of printable characters, limited to a set of 64 unique characters. - Wikipedia

Binary to text data is presented in an ASCII format. Your string or text will be converted into a binary data then it will again transform into an ASCII characters which can be understood by any human. But since it's an encoding scheme, the characters that are being displayed are not easily identifiable by any normal human. 

You can read the letters or characters but not the actual encoded word or sentence. There are online base64 encoders available to do the job for you. The base64 encoding is mainly used for security and safety purpose in a particular organization. So only those will be able to recognize the program or the code, who have knowledge of decoding it. 

Honestly speaking, nobody does this manually nowadays. There are base64 decoder online tool which is way more convenient and beneficial than doing the things manually.

Maybe in the early days of computers and programming, people used to do things manually but not now. Everyone use Base64 to JSON Converter Online Free tool to make things faster and reliable.

Here are some reasons why programmers use base64:

  • Binary-to-Text Conversion
  • Compatibility with Text-based Systems
  • Data Integrity during Transmission
  • Web Development (Embedding Images)
  • Basic Authentication (Insecure without Encryption)
  • Storage Efficiency (with some trade-offs)

Base64 is mainly used for secure data transfer with an email protocol known as SMTP. Whatever the data user is sending is first converted into binary then to human readable text process which is nothing but base64 encoding.

These are some areas where base64 encoding is widely used:

  • Email Attachments
  • Data Transmission
  • Data Storage
  • APIs and Web Services
  • Authentication
  • HTML and CSS

Base64 is widely used in the computer networks and communication systems that requires encoding scheme.

What is JSON?


JSON (JavaScript Object Notation) is a widely used data interchange format in modern software development. It is mainly used for sharing the informational data in a key value pair. 

JSON is an open standard file format and data interchange format that uses human-readable text to store and transmit data objects consisting of attribute–value pairs and arrays. It is a commonly used data format with diverse uses in electronic data interchange, including that of web applications with servers. -Wikipedia

JSON is a part of web development that requires a lot of informational data. You can learn more about web development with JSON online.

Example of why do programmers use JSON:

- Data Interchange
- Human Readable and Writable
- Language Agnostic
- Data Structure Representation
- Web Development
- Database Storage
- Standardization

Some popular areas where JSON is used:

  • Data Interchange Systems
  • Configuration Files
  • Logging
  • NoSQL Databases
  • Mobile App Development
  • Internet of Things (IoT)
  • Testing and Mocking

How to use Base64 to JSON Converter?

It’s very simple and anyone can use our Base64 to JSON Converter online without downloading anything.


  1. Enter encoded Base64 string or text
  2. Click on ‘Convert’ button.
  3. Click on ‘copy to clipboard’ button.
  4. Now, use the JSON format wherever you want.
  5. Done!

You just have to put the input text into a text area where it says “Enter Base64 string here…” and then you have to click on Convert button.

The tool will start its process to convert Base64 to JSON online. The process is superfast and you will see the output instantly. Like within a few seconds.

But remember that you should not add any extra spaces, characters or any other string which was not initially included in the encoded base64 string. The tool will throw an error something like this: “Invalid Base64 or JSON format!”

Also, you should not put normal or decoded base64 string. It will not work either. The tool is specifically made for the purpose of converting encoded base64 to JSON online. The JSON format is like a key value pair as we already know.

So if everything is fine, you will see the correct JSON format as an output.

How does this Base64 to JSON Converter Online Tool work?

That thing is a secret!

Just kidding!

Our programmers made this tool using a JavaScript as a main functional coding. So the tool is solely running in the html language itself. It runs directly in the browser so need to download or install anything separately.

The logic and the coding mechanism is hard to explain here since it’s at the programmer’s end. But I can tell you one thing that whatever the input user has entered will first be decoded and then formatted into a JSON. The algorithm knows what to do, how to do, when to do and what not to do. That’s the best part actually.

The tool will start its process automatically once the user input is identified by the algorithm and the tool will then convert base64 to JSON online for free.

You don’t even have to pay anything. It’s totally free of cost. Anyone can use it as much as they want.

Why do we need to convert Base64 to JSON online?

We need to convert Base64 to JSON online because there are situations where we receive data in Base64 format and we need to process or manipulate it using JSON (JavaScript Object Notation), a lightweight data-interchange format.

Base64 is a binary-to-text encoding used for representing binary data in ASCII characters, while JSON is a human-readable format for structured data.

Converting Base64 to JSON helps us work with the data more efficiently and in a format that is easier to understand and manipulate. Online tools provide a convenient way to perform this conversion without requiring any software installation or programming knowledge.

Sometimes, programmers get data directly into a base64 format and it’s not easily readable since the encoding has a different representation than normal reading format.

And to make it more readable. Programmers have to use Base64 to JSON converter online.

Many programmers encode JSON to base64 format for various reasons like security, safety, etc.

So to prevent the stealing of code or I should say, not to display publicly that easily, many coders want their JSON format to be encoded in base64.

Then that data will be converted into a combination of multiple characters. No normal human could ever recognize or identify what it says.

Now, to read the encoded data, coders have to first convert base64 to JSON format. And our tool does this thing automatically in a single click.

It saves time, effort and money too.

The main benefit of using our Base64 to JSON converter is to access data easily.

But keep in mind that our tool cannot guarantee the safety or security of your data. If someone has already stolen your data or program, then our tool has no idea who is the actual owner or source of the data.

This tool is just a machine program to convert Base64 string to JSON online.


The conclusion is that our tool will convert Base64 to JSON online for free.

We don’t ask for money and there are no hidden charges as well.

Just use it for your own good or for professional use, we will never ask anything return.

But we want you to share this tool with your people so they will get the benefit of this tool.

Save or bookmark this tool for the future use.
