Here is a list of the best free online JSON to Base64 converter websites. JSON (JavaScript Object Notation) is a lightweight and human-readable data interchange format. Whereas Base64 is an encoding technique that encodes the binary data into ASCII string format. Converting JSON to Base64 provides you a more compact and easily transmissible data. While converting JSON to Base64 manually is possible, it can be time-consuming and with possibilities of errors. Instead of that, you can use online tools to do the same.

You can simply provide the JSON input to the converter tool whether it is raw code, JSON file, or a URL. Then the output gives you the Base64 data that you can copy or download.
