Common errors and how to fix them
Hex must have an even number of digits
Each byte is two hex digits. A missing or extra digit means part of a byte is missing.
These bytes are not valid UTF-8 text
The bytes don't form valid UTF-8, so they might be binary data or another encoding rather than text.

Text to Hex & Binary Converter FAQ
The text is encoded as UTF-8 bytes, and each byte is written as two hexadecimal digits. "A" is the byte 65, which is 41 in hex.
In UTF-8, characters outside basic ASCII use 2 to 4 bytes. é is C3 A9, and most emoji use 4 bytes.
For the first 128 characters they're the same number. Beyond that, ASCII has no codes, so the tool shows the Unicode code point — é is 233 (U+00E9).
Yes. Spaces, commas and 0x or \x prefixes are ignored when converting hex back to text.
Each UTF-8 byte is written as 8 binary digits, so "H" (72) becomes 01001000.
No. Conversions happen in your browser.
