Each hexadecimal byte pair identifies one byte. A text interpretation also needs a character encoding.

The main result lists decimal bytes. Preview UTF-8 interprets them as text; copy and save use the main result.

  • Read a UTF-8 string that a log, packet capture, or database export stored as hex.

Decode UTF-8 bytes for café

Input: 63 61 66 c3 a9

Settings: Delimiter Auto

Result: café

The final two bytes encode é in UTF-8.

Choose delimiters and inspect the byte preview

  1. Paste the byte values.
  2. Keep Delimiter Auto for mixed supported separators.
  3. Inspect the byte result before copying it.
  • Malformed pairs can produce partial bytes without an error.
  • Hexdump offsets and text columns become unwanted input. Use Hexdump Decoder for that format.
  • The text preview does not support Latin-1.
