About Text to Hex
Hexadecimal is the format everyone reaches for when looking at raw bytes, because the mapping is so clean: one byte is exactly two hex digits, so byte boundaries stay visible in a way they never are in decimal.
This converter shows the actual UTF-8 bytes of your text, space-separated by byte. That makes it easy to compare against a hex editor, a network capture or a debugger without mentally regrouping digits.
Decoding is tolerant of the formats hex usually arrives in — 0x prefixes, colons, commas and line breaks are all stripped before conversion.
Frequently asked questions
What is hex used for?
It is the standard shorthand for raw bytes: colour codes, memory dumps, file signatures, checksums, MAC addresses and network packets are all written in hex because two digits map neatly onto one byte.
Can I paste hex with 0x prefixes?
Yes. 0x prefixes and any non-hex separators are stripped before decoding, so most formats you copy from a debugger will work.
Why does one character give more than two digits?
Because it is more than one byte in UTF-8. Anything outside basic Latin takes two to four bytes, so you get two to four pairs of hex digits.
Is hex the same as a hash?
No. Hashes are usually displayed as hex, but hashing is a one-way transformation you cannot reverse. Hex encoding is a plain representation of the bytes and reverses perfectly.
Is it free?
Yes — unlimited use, no sign-up, no watermark and no limit on how many times you run it.
