toolbox/Utilities/base64 / url codec

Base64 / URL codec

Unicode-safe Base64 and percent encoders/decoders.

// output appears here

about this tool

Encodes UTF-8 text to Base64 via TextEncoder (emoji-safe), decodes it back the same way, and percent-encodes/decodes URL components with encodeURIComponent semantics.

Errors on malformed input are surfaced rather than producing mojibake.
