FAQ

What is Base64?

Base64 is an encoding scheme that represents binary data using a limited set of ASCII characters. It is commonly used for data transport and embedding.

Is my data uploaded?

No. Encoding and decoding are performed locally by your browser. This tool does not need an account, server, or API.

Does it support Unicode?

Yes. Text encoding uses UTF-8, so characters such as emoji and non-Latin scripts are supported.
