Frequently asked questions

What is Base64 used for?

Base64 turns binary data into plain ASCII text so it can travel through channels designed for text: JSON, XML, e-mail, data URIs in HTML/CSS.

Does it work with non-Latin characters?

Yes. Text is treated as UTF-8, so Cyrillic, Chinese, emoji and any other Unicode characters encode and decode correctly.

Why do I get a decode error?

The input is not valid Base64 — check for missing padding (=), line breaks or characters outside the Base64 alphabet.

Is Base64 encryption?

No. Base64 is an encoding, not encryption — anyone can decode it. Never use it to protect secrets.
