Base64 Encoder / Decoder
Encode plain text to Base64, decode Base64 back to text, and copy the result.
Use this Base64 Encoder / Decoder when you need to inspect tokens, encode small snippets for configuration, decode API examples, or check whether a value is readable text.
Base64 is useful for transport and representation, but it is not a security boundary. Do not treat Base64-encoded values as private secrets.
FAQ
Base64 Encoder / Decoder questions
Does this Base64 tool upload my input?
No. Encoding and decoding run locally in your browser, and the tool does not send your input to a server.
Is Base64 encryption?
No. Base64 is an encoding format, not encryption. Anyone can decode Base64 text unless it is encrypted separately.
Can Base64 handle Unicode text?
Yes. This tool uses UTF-8 encoding, so it can encode and decode ordinary Unicode text.
