Character Set & Binary Radix Transformation
Encoders and decoders map binary byte sequences or text characters to alternative radix representations (such as Base64, Base62, Hexadecimal, or URL Percent-Encoding). Decoding performs the inverse mathematical mapping to restore the original plain text or binary buffer. Because processing occurs entirely within local browser memory, API keys, sensitive tokens, and session credentials never leave your machine.
