Base64 Encoder / Decoder
Encode text to Base64 or decode Base64 back to text, with full Unicode support.
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?
