§ decode

decode.

Paste an unknown string, get parallel decode attempts. Each candidate that succeeds is scored by the printable-character ratio of its output, so the most plausible interpretation sorts to the top.

tried

base64, base64url, base32, hex, URL-encoded, Unicode escapes (\\uXXXX), JWT (3-segment).

ranking

printable ratio is a heuristic, not proof. a high score means "this output is reasonable text", not "this was the original encoding".
