How it works

Pairs of hexadecimal digits combine high and low nibbles into bytes; optional separators are removed only in permissive mode. Text output uses a selected character encoding and may fail for arbitrary binary.

  • Two digits make byte boundaries explicit.
  • Odd lengths are rejected rather than padded.

When to use this

Hash inspection, packet dumps, and key debugging decode hex.

Edge cases

  • An odd digit count cannot form bytes.
  • Separators valid in permissive mode can be invalid in strict mode.
  • Binary bytes may not be UTF-8 text.
