Base32 Encode / Decode

Encode text to Base32 (RFC 4648) or decode Base32 back to text.

Base32 Encode / Decode converts plain text into the RFC 4648 Base32 alphabet and back again with a single click. Unlike hexadecimal, Base32 stays readable over the phone, avoids ambiguous characters like the digit zero and the letter O, and survives the case folding that some systems apply, which is why it appears in time based one time password secrets, fingerprint strings and archive file names. Paste your text and the panel shows the encoded output, its length, and how many bits each character carries. The decoder accepts input with or without padding, ignores line breaks from wrapped output and reports invalid characters instead of silently failing. You can switch between the standard and extended alphabets, copy the result instantly, and process everything locally in the browser. It is a quick way to move short secrets through tools that only accept plain letters and digits.
