Text is encoded as UTF-8 bytes, including Unicode characters and emoji.
Conversion happens entirely in your browser. HEX input is decoded as UTF-8 and invalid byte sequences are rejected instead of replaced silently.
How it works
UTF-8 bytes, made readable.
Encode text into uppercase hexadecimal bytes or decode valid UTF-8 HEX data back into plain text. Everything stays in this browser.
