The Base32 Encoder / Decoder converts text to and from Base32 (RFC 4648) in real time using the standard A-Z2-7 alphabet. It handles UTF-8 correctly, so emoji and non-Latin scripts round-trip cleanly. Output is padded with = to 8-character blocks, and the decoder accepts text with or without whitespace and padding.

Base32 is widely used where case-insensitive or human-friendly encodings matter: TOTP secrets, DNSSEC keys, PGP fingerprints and some hash displays. Encode mode turns any text into its Base32 form; decode mode reverses the process. Everything runs locally with plain JavaScript - nothing is uploaded, so it is safe with sensitive payloads.
