About the Base64 Encoder / Decoder

Convert text to Base64 and back. Unicode is handled correctly, so emoji and non-Latin scripts survive the round trip, and a URL-safe variant is available for tokens that travel in query strings.

Frequently asked questions

Is Base64 encryption?

No. It is an encoding, not a cipher — anyone can decode it. Never use it to protect secrets.
