JSON to Base64 Converter

World's simplest json tool

Free online JSON to base64 converter. Just load your JSON in the input field and it will automatically get converted to the base64 encoding. In the tool options, you can split the base64 into chunks of a certain length or output it as a single continuous string of characters. Additionally, you can generate JSON data URIs by appending the MIME type "data:application/json;base64" at the beginning of the base64 data. Created for developers by developers from team Browserling.

What is a JSON to Base64 Converter?

learn more about this tool

This tool converts JSON data into base64-encoded data. Base64 is an encoding scheme that changes the representation of any data to only 64 ASCII characters. This is useful when you need to embed complex JSON data structures into other data formats (such as XML or HTML) or transmit them through protocols that use a similar syntax to JSON. This tool also allows you to chunk the encoded output. If you enable chunking in the options, then you can set the size of each chunk, and each chunk of this length will be printed on a new line. Additionally, you can create data URIs, which enable embedding data directly into URLs, which is useful for transmitting small JSON files without needing to load them from a server. The reverse operation of converting base64 to JSON data can be done with our Convert Base64 to JSON tool. Json-abulous!

Convert a JSON Object to Base64

In this example, we convert a simple JSON data structure with a single key-value pair ("hello": "world") into a base64-encoded string. The JSON object is transformed into a sequence of characters from the base64 alphabet and displayed as a single continuous line.

{"hello" : "world"}

Generate a Data URL Create a data URL with the "data:application/json;base64" MIME type.

Chunkify Base64 Output

This example encodes JSON data with the chunkify-output option enabled. It converts a JSON file representing chessboard numbers and letters into base64 and splits the output into chunks of 16 characters each for better readability.

{ "numbers": [1,2,3,4,5,6,7,8], "letters": ["a","b","c","d","e","f","g","h"] }

Convert a JSON Array to a Data URI

In this example, we convert a JSON array with popular cryptocurrency names into the base64 format. We also enable the data URL option and obtain a base64 file that's prefixed with the JSON MIME type "application/json". Additionally, we split the data into chunks, each containing 32 characters.

["Bitcoin", "Ethereum", "Tether", "BNB", "Doge"]
