{ } How to use

  1. Paste or type your text.
  2. Select Process to get its bytes as hexadecimal.

{ } How it works

Hex Encode works on the text you provide. Select Process ▸ and it runs entirely in your browser — nothing is uploaded to a server — then shows the result in the Output panel.

Input

  • Text input — paste or type your input in the left panel (use Sample for an example)

Output

TXT text — copy or download it from the Output panel.

{ } Common uses

  • Inspect the exact bytes behind a string, invisible characters included.
  • Produce a hex literal for a fixture, a test or a protocol field.
  • Confirm how many bytes a particular character actually costs.

{ } Limitations

  • The text is read as UTF-8, so one character can become several bytes — an accented letter is two, most emoji are four.
  • The output is continuous lowercase hex: there is no option for separators, uppercase digits or an 0x prefix.

{ } FAQ

Is my data uploaded to a server?

No. Everything runs locally in your browser — your files never leave your device.

Can I process more than one file at once?

This tool works on one input at a time.

Is this tool free?

Yes — it’s completely free and needs no sign-up.

Can I get spaces between the bytes?

Not here. Binary Encode groups its output one byte at a time if you need the boundaries visible.
