Limits and edge cases
- Text is encoded as UTF-8 bytes, so ASCII characters use one byte each while accented letters and emoji use more.
- The separator accepts escapes: type \n for a new line, \t for a tab, or leave it empty for no separator.
- Tick Uppercase digits to show A–F instead of a–f; the values are identical either way.

How do I convert text to hex?
Paste your text into the input box and the hexadecimal output appears instantly. Copy it or download it as a .txt file.
What encoding is used?
Text is encoded as UTF-8 bytes, and each byte is shown as a two-digit hex pair. ASCII characters use one byte each; accented letters and emoji use more.
Can I change the separator between hex values?
Yes. Type any separator such as a space, comma, or empty for none. Use \n for a new line and \t for a tab.

No. Conversion runs in your browser with JavaScript and nothing is sent to a server. Inputs under 200 KB are kept in your browser's local storage so they are still there when you come back.
