The Text ⇄ Base64 tool converts plain text into Base64-encoded form and decodes Base64 back into readable text. Base64 encoding is commonly used to safely transmit binary or text data through systems that only handle plain characters, such as JSON, configuration files, or certain APIs. It does not encrypt the content, but it does convert it into a transport-friendly format.

You can enter any text and encode it into Base64, then copy the result for use in your code or configuration. You can also paste an existing Base64 string and decode it to see the original content, which is helpful when debugging API payloads or inspecting stored data. The tool uses UTF‑8 aware conversion so that non-English characters are handled correctly in most modern browsers.

All encoding and decoding happen in your browser, and no data is stored or logged. Because Base64 is not a security feature, you should avoid treating it as a form of encryption. This tool is best used for integration, testing, and learning how simple encodings work behind the scenes.
