How do you convert ASCII to hex?

An ASCII to hex converter shows each character of your text as its hexadecimal byte value. Snabbit prints two hex digits per byte, so the ASCII letter “A” becomes “41”. UTF-8 encoding means accented and non-ASCII characters convert too. It all happens in your browser, so your input is never uploaded.

How to use the ASCII to Hex

  1. 1 Type or paste your ASCII text.
  2. 2 The hexadecimal output appears instantly.
  3. 3 Each character becomes two hex digits (more for non-ASCII).
  4. 4 Copy the hex string.

What you can use it for

  • Encoding ASCII as hex for protocols.
  • Building hex byte strings for tests.
  • Inspecting character byte values.
  • Learning ASCII and hexadecimal.

Frequently asked questions

What hex value does a letter get?
Each ASCII character maps to its byte value in hex — for example A is 41, a is 61 and the space is 20.
Does it work for non-ASCII characters?
Yes. Text is UTF-8 encoded first, so accented letters and symbols become several hex bytes.
How do I reverse it?
Use the Hex to ASCII converter to turn the hex values back into characters.
