How do you convert UTF-8 to hexadecimal?
A UTF-8 to hexadecimal converter shows the hex byte values behind text. Snabbit encodes your text as UTF-8 and prints two lowercase hex digits per byte, separated by spaces, so “Hi” becomes “48 69”. Accented and emoji characters expand to several bytes. It runs in your browser, so your text stays private and is never uploaded.
How to use the UTF-8 to Hex
- 1 Type or paste your UTF-8 text.
- 2 The hexadecimal byte values appear instantly.
- 3 Each byte is shown as two lowercase hex digits.
- 4 Copy the hex string.
What you can use it for
- Inspecting the UTF-8 byte values of a string.
- Building hex byte literals for code or tests.
- Debugging character-encoding problems.
- Comparing how two strings encode at the byte level.
Frequently asked questions
Why might one character produce several hex values?
Text is UTF-8 encoded first. ASCII characters are one byte (two hex digits), while accented letters and emoji use two to four bytes, so they show as several hex pairs.
Is the output upper or lower case?
It uses lowercase hex digits a–f. Hex is case-insensitive, so you can uppercase the result yourself if a target system expects capitals.
How do I reverse it?
Paste the hex into the Hex to UTF-8 converter to decode the byte values back into text.
