FAQ
Base64 Encoder / Decoder FAQ
Does it support Unicode text?
Yes. The encoder and decoder use UTF-8, so text with international characters is handled correctly.
What is URL-safe Base64?
URL-safe Base64 replaces characters that can be awkward in URLs, making the output easier to use in query strings, tokens, and web-safe identifiers.
