Text to HEX Converter

What are these pairs like C3 A9?

Error logs, developer tools and corrupted files opened in a text editor sometimes show data in hexadecimal, or HEX: pairs of digits and letters from 0 to F, each pair standing for one byte. Jood's converter turns words into those values and back again, so you can see what is really inside the data.

How to use it

1. Choose "text to HEX" or "HEX to text".
2. Type the text or paste the values into the input box.
3. Click "Start Now", then copy the result.

The word Jood becomes 4A 6F 6F 64, while é becomes C3 A9: two bytes for one letter, because accented letters take two bytes in UTF-8, and the euro sign € takes three (E2 82 AC).

Flexible input

• Values are accepted in upper or lower case, with or without spaces: c3a9 and C3 A9 mean the same thing.
• The 0x prefix used in programming languages is stripped automatically, so 0x4A 0x6F gives Jo.
• If the number of digits is odd, or the values do not form valid text, the tool tells you.

A practical use: decoding mangled characters

Ever seen "é" where "é" should be, on a website or in a CSV file opened in Excel? That happens when UTF-8 text is read as if it were in an older encoding. Convert the correct letter to HEX and you see its real bytes: é is C3 A9. A program that reads those two bytes as two separate characters shows à followed by ©. Knowing the bytes helps you or a developer pin down where the text was misread.

These are also the values you see in encoded web addresses, such as %C3%A9. To encode a whole address, use the slug generator and URL encoder.

Not the same as HEX colors

Color codes like #4F46E5 are hexadecimal too, but they stand for red, green and blue levels, not letters. For those, use the HEX to RGB converter. The same tool also offers binary and decimal modes in its list. Your input is sent to Jood's server, converted, and not stored.
