Frequently asked questions

What is Base64 used for?

Base64 encodes binary or text data using 64 printable characters so it can travel safely through systems that expect text, such as email or data URLs.

Does it handle emoji and accented characters?

Yes. The encoder is UTF-8 aware, so Unicode characters round-trip correctly.
