Base32 Decode
Paste a Base32 string and recover the original UTF-8 text. The decoder accepts the standard RFC 4648 alphabet (A-Z, 2-7), is case-insensitive, and tolerates missing or extra = padding. Invalid characters are reported clearly so you can fix the input. Useful for inspecting TOTP secrets, decoding Base32-encoded identifiers, or debugging anything that used base32-encode. Runs entirely in your browser.
