Not encryption
Why the internet quietly speaks Base64
Email, web tokens and data URLs were built to carry plain text, not raw binary. Base64 solves that by re-packing any data into just 64 safe characters — letters, digits, + and / — so it survives systems that would otherwise mangle it.
One myth worth killing: Base64 is not encryption. It's trivially reversible and hides nothing. It's for transport and compatibility, never for keeping secrets.
Frequently asked questions
Is Base64 secure?＋
No. It only re-encodes data and anyone can decode it. Use real encryption for anything sensitive.
Does it handle emoji and accents?＋
Yes — it encodes full Unicode (UTF-8), so emoji and accented characters round-trip correctly.
