Frequently asked questions

What is Base64 used for?

It's a way to represent binary or text data using only readable ASCII characters — commonly used in emails, data URLs, and APIs.

Why does decoding sometimes fail?

Decoding fails if the input isn't valid Base64 — check for missing characters or extra spaces copied in by accident.

Does this support special characters and emoji?

Yes, text is UTF-8 encoded before conversion, so accented letters and emoji round-trip correctly.
