Text to Hex

Type text and see its UTF-8 bytes as hexadecimal — with a choice of separator (spaces, none, or 0x prefixes). Useful for debugging encodings, crafting byte payloads or teaching how text becomes bytes.

Frequently asked questions

Is my text sent anywhere?

No. The transformation happens in your browser with plain JavaScript — nothing you type or paste leaves your device.

Which encoding do the hex bytes represent?

UTF-8 — the encoding used by the web. 'A' becomes 41, '€' becomes e2 82 ac.
