About Detect Encoding
Detect Encoding analyzes a string's pattern to guess how it was encoded — e.g. only 0/1 (binary), only hex, containing %XX (URL), dots & dashes (Morse), or Base64/Base32/Base58 patterns.
This detection is heuristic: some patterns can match more than one encoding, so the tool gives a list of candidates rather than a definitive answer. Once you know the candidate, use the matching decode tool.
