How to encode and decode hexadecimal
Convert UTF-8 text to hex bytes, or hex back to text, with Toolora’s Hex Encode / Decode tool.
What hex encoding is for
Hex is a readable way to show raw bytes in logs, firmware dumps, and binary protocols. Each byte becomes two characters (0–9, a–f).
Steps
1) Open Hex Encode / Decode. 2) Choose Text → Hex or Hex → Text. 3) Paste input (0x prefix is allowed when decoding). 4) Click Run. Conversion stays in your browser.
