What is Base64 Tool?
Base64 Tool converts readable text or encoded Base64 data in either direction. Base64 is an encoding format rather than encryption, so this utility is best used for inspecting data URLs, basic authorization fragments, email payloads, configuration values, and API fields that transport binary or textual content in an ASCII-safe representation.
How to use Base64 Tool
Enter text or Base64 data, choose whether to encode or decode it, and copy the converted result.
When is Base64 Tool useful?
Base64 Tool is useful when working with API payloads, configuration values, encoded text, or development data that uses Base64 representation.
Example
A practical example is encoding a short JSON string to Base64 and decoding it again to confirm the original content.
Practical notes
Decoded Base64 may contain private information even when the encoded value looks unreadable. Do not treat it as a security boundary, and avoid pasting access tokens or production secrets into documentation, tickets, or public examples after decoding them.
