Frequently asked questions
What is Base64?
Base64 is an encoding that represents binary data using 64 printable ASCII characters, often used to embed data in text formats.
Does this tool support Unicode?
Yes. Input is encoded as UTF-8 before Base64 conversion, so emoji and non-Latin characters round-trip correctly.
Is Base64 encryption?
No. Base64 is only an encoding. It can be decoded by anyone and provides no security or secrecy.
