Encoding text as Base64

Text is encoded as UTF-8 bytes and then Base64 in your browser. This is useful when a text field must carry an encoded value.

Output behavior and limits

Base64 is reversible encoding, not encryption, and generally increases the amount of data. This workspace accepts text rather than arbitrary binary file uploads.

Encoding hello produces aGVsbG8=. Decode the result to verify the text, including non-English characters, before using it in an API request.
