Your text is processed locally in your browser. It is not uploaded to a server.

Base64 is an encoding format, not encryption. Do not use it to protect sensitive information.

Encoding uses UTF-8, so Hausa characters, accented text, and emoji are preserved. Decoding accepts optional ASCII whitespace but rejects invalid Base64 or invalid UTF-8.

All processing is local. Related tool: JSON Formatter & Validator.
