Frequently asked questions
Is Base64 a form of encryption?
No, and this matters: it is an encoding, reversible by anyone in one click. Never use it to hide a password or a token.
What is Base64 for?
Carrying binary data through channels that only accept text, such as data URIs in CSS, email attachments and JSON payloads.
Does it handle accents and emoji?
Yes. The text is treated as UTF-8 before encoding, so non-Latin scripts and emoji survive the round trip unchanged.
