How do you convert text to hex?
Hexadecimal is base 16: every byte fits in exactly two digits, 00 to ff. This converter encodes your text as UTF-8 and writes those pairs space-separated, so “Hello” comes out as “48 65 6c 6c 6f”. Output is lowercase, which most tools accept; uppercase it later if a spec demands it. Multi-byte characters expand honestly: “€” becomes “e2 82 ac”, three bytes, not one mystery value.
How to use the Text to Hex
- 1 Feed the converter any string, short or long.
- 2 Scan the space-separated hex pairs it prints, two digits for every byte.
- 3 Note that accents and emoji yield several pairs each because encoding is UTF-8.
- 4 Take the hex wherever you need it.
What you can use it for
- Inspecting the byte values behind a string.
- Building hex literals for code or config.
- Debugging character-encoding issues.
- Creating colour or data values from text.
Frequently asked questions
Is the output upper or lower case hex?
Lowercase (a–f). Hex is case-insensitive everywhere that matters, but if a checksum spec or register map insists on uppercase, transform it after copying.
How are multi-byte characters handled?
UTF-8 first, always. “é” shows as c3 a9 and a typical emoji as four pairs, which is exactly what a file on disk would contain.
Can I reverse it?
Paste the pairs into the Hex to Text converter. It tolerates the spaces this tool inserts, so no cleanup is needed.
