What to enter
| Input | Meaning and units |
|---|---|
| Text or encoded input | Text is processed in your browser. Maximum input: 1 MiB of UTF-8 text. |
| Calculation mode | encode/decode |
Understanding your result
The output applies the selected format or address convention. Encoding is not encryption; a valid address representation does not establish availability, reachability or security.
Common mistakes
- Using a different alphabet, padding, base, delimiter or address-prefix convention than the tool expects.
Check your calculation
- Where a reverse operation exists, round-trip a short known example. Compare structural results with the reference example rather than executing decoded text.
Calculation checks, sources and review limits
What UTF-8 bytes encode this text, or what text do these hexadecimal bytes represent?
Convert Unicode text to hexadecimal UTF-8 bytes or decode valid UTF-8 bytes into text.
Common uses
- Convert Unicode text to hexadecimal UTF-8 bytes or decode valid UTF-8 bytes into text.
How it works
UTF8-encode Unicode scalar sequence and emit byte hex; inverse strict UTF8 decode.
Worked example
Enter Text or encoded input: é; Calculation mode: encode. The result is Hex: C3 A9.
FAQ
What UTF-8 bytes encode this text, or what text do these hexadecimal bytes represent?
UTF8-encode Unicode scalar sequence and emit byte hex; inverse strict UTF8 decode.
What assumptions and limits apply?
No Unicode normalization is implied; malformed UTF8 rejected.
