Hex Converter

Hex is a common way to show raw bytes: each byte is two hex characters (00–FF). Protocol docs, memory dumps, and simple crypto examples all use hex strings. This tool converts both ways between text and hex for quick comparison.

Tips for use

Text → hex shows the byte-level representation; hex → text checks whether a copy is complete. Hex length should be even; spaces can sometimes be ignored, but clean continuous hex is preferred.

For UTF-8 byte semantics, also use the on-site UTF-8 tool and interpret results with the intended encoding.

Tips

  • Hex is a notation — not a hash, and not encryption.
  • Case usually does not matter, but teams should pick one style for easier diffs.
