- 2Choose separators, uppercase and the 0x prefix.
- 3Copy the hex, or click Swap to decode it back.
Two digits per byte
Text is encoded as UTF-8 and each byte becomes two hex digits: “Hi” is 48 69. Letters beyond plain English take two to four bytes, so é is c3 a9.
Decoding is flexible
Hex can be pasted with spaces, commas, colons, 0x or \x before each byte, or as one long run of digits.
Formats
Turn on uppercase for C3 A9 instead of c3 a9, and 0x for C-style 0x48 0x69.
