Convert JSON to Base64 encodes any JSON object into Base64 safely in your browser. The Convert JSON to Base64 tool supports live preview, file import, and export.
How to Use:
Start by pasting a valid JSON object into the Input JSON box. You can also import a .json or .txt file using the Choose File button. The moment you enter valid JSON, Convert JSON to Base64 will automatically encode it.
The output appears in the Base64 Output box. It’s encoded using UTF-8 and ready to be used for APIs, tokens, or embedded data. If you want to copy the result, click Copy Output. To save it, click Export to File it downloads as a .txt file containing the Base64 string. Use Clear All to reset everything and start again.
What Convert JSON to Base64 can do:
It instantly turns your JSON into a Base64-encoded string using native browser encoding. You can take full JSON objects whether from logs, config files, or webhooks and generate Base64 versions without needing external tools. It’s perfect for embedding JSON in URLs, passing data securely, or prepping it for transport. The tool gives you live feedback, flashes the output on update, and shows a character count so you know exactly how long your encoded result is.
Example:
Input:
{ "name": "Alice", "email": "[email protected]" }Output:

Convert JSON to Base64 is ideal for developers working with APIs that require Base64 payloads or encodings inside tokens. It’s also great when you’re debugging or building systems where you need to embed structured data into headers or query strings. Everything runs client-side and gives you instant results with no fuss.
Useful Tools & Suggestions:
Before encoding, Stringify JSON should be run so the structure becomes a single string. Then, once it’s in Base64, Decode Base64 to Unicode can be used if you ever need to check or reuse the contents later.
