Hex decode

POST /api/hex-decode

Decode hex-encoded bytes back to binary. Tolerant of whitespace, the `0x` prefix, and `:` separators (such as colon-separated MAC-address style hex).

Parses a hex string and returns the original bytes. Tolerant of: - Whitespace and newlines (stripped before decoding). - An optional `0x` prefix. - Colon separators (e.g. `aa:bb:cc:dd` — the format `xxd` and `tcpdump` produce). Mixed case is fine. The number of hex characters must be even.
