About Hex ↔ String
Hex strings represent raw bytes in a readable form—common in crypto dumps, firmware logs, and protocol debugging.
toco.tools encodes text to hex and decodes hex back to strings using UTF-8 bytes, including multilingual text.
Invalid hex digits or odd-length sequences may fail to decode. Very large inputs can slow the browser.
How to use
