Text to Hex Online

Updated 2026-10-24

Convert text to hexadecimal online for free. Type any string and SnapTools shows its UTF-8 bytes in hex, character by character, with spaces between bytes for readability, ready to copy or download. Everything runs in your browser, so your text is never uploaded.

Seeing a string as raw hex bytes is essential when you are debugging an encoding problem, building a hex literal for code, or checking exactly how a Unicode character is stored. Because the text is encoded as UTF-8 first, you can see clearly why an accented letter or emoji takes more than one byte, and reverse the whole thing any time with Hex to Text.

// how to use

  1. 1 Type or paste text into the input panel on the left.
  2. 2 SnapTools converts each character to its UTF-8 hexadecimal bytes as you type.
  3. 3 Copy or download the hex output, or switch to Hex to Text to reverse it.

// faq

Is my text uploaded to a server?
No. The conversion runs entirely in your browser, so your text never leaves your machine.
What encoding is used?
Text is encoded as UTF-8 first, then each byte is shown in hexadecimal. This means characters outside ASCII (accents, emoji, symbols) expand to two or more bytes.
Why does one character produce several hex bytes?
In UTF-8, characters above the basic ASCII range are stored as multiple bytes, so a single symbol like € becomes three hex values (e2 82 ac).
Can I convert the hex back to text?
Yes. Use the Hex to Text tool, which accepts hex with spaces, colons, or a 0x prefix and decodes it back to readable text.
Is the output upper or lower case?
Hex bytes are shown in lower case and separated by spaces, a widely readable convention. The Hex to Text tool accepts either case on the way back.
