What to check

  • Text conversion uses UTF-8, so non-Latin characters may use multiple bytes.
  • Hex input can include spaces, commas, line breaks, and 0x prefixes.
  • If decoded text looks wrong, the source bytes may use another encoding.
  • Color mode supports #RGB and #RRGGBB values.

When hex conversion helps

Hexadecimal is a compact way to show bytes. It is common in API logs, packet dumps, file headers, color values, and debugging workflows.

Usage notes

  • One byte is represented by two hex digits from 00 to FF.
  • Text is encoded into UTF-8 bytes before it is displayed as hex.
  • Decoding hex splits the value into byte pairs and interprets them as UTF-8.

Frequently asked questions

Can I paste values like 0x47,0x6f?expand_more

Yes. Prefixes, spaces, commas, and line breaks are normalized before decoding.

Why do some characters create long hex output?expand_more

UTF-8 uses multiple bytes for many non-Latin characters, so the hex output becomes longer than the character count.
