How to use the Random Hex Number Generator

  1. Enter or paste your input in the box (or set the options, if the tool needs no input).
  2. Adjust the options to match what you need — the result updates as you type.
  3. Copy the result or download it, and keep editing if you want a different outcome.

What does this tool do?

Choose how many values to create and how many hex digits each has, with optional 0x prefix and upper-case letters. Values come from your browser's secure random number generator, so they are suitable for test tokens, but check your requirements before using them as real secrets.

Everything runs in your browser, so nothing you enter is uploaded or stored.

Why use it?

  • Free, with no sign-up and no limits.
  • Instant results as you type.
  • Private — your data stays on your device.
