What Is Text to Hex Encoding?

Every text character is stored in memory as one or more bytes. Text to hex encoding expresses those bytes as two-digit hexadecimal values, making it easy to inspect, transmit, or debug raw string data. The letter H is byte 48 in hex; the emoji 😊 is four bytes: F0 9F 98 8A.

This tool uses UTF-8 encoding, the internet's universal standard. For the reverse operation see our Hex to Text Converter. To view all character values side by side, check the ASCII Table.

?How It Works

  1. 1

    Select Text to Hex or Hex to Text using the tabs above.

  2. 2

    Type or paste your text. UTF-8 bytes appear as hex pairs instantly.

  3. 3

    Open Options to pick output case (FF vs ff) and delimiter style.

  4. 4

    Use Swap to reverse direction — great for round-trip verification.

  5. 5

    Copy or download the hex output with one click.

Common Use Cases

  • Web Dev: Encode strings to hex for URL escaping, Content-Security-Policy nonces, or cookie values.
  • Networking: Represent packet payloads as hex for Wireshark filters and firewall rules.
  • Security: Inspect or construct hex-encoded shellcode, payloads, and hash comparisons.
  • Databases: Store binary data as hex strings in SQL VARBINARY or BLOB columns.

Frequently Asked Questions

How do I convert text to hex?
Type or paste any text into the input box. Each character is instantly encoded as a two-digit hexadecimal value using UTF-8. The result updates in real time as you type.
What delimiter options are available?
Open the Options panel to choose: space-separated (48 65 6C), no separator (48656C), or 0x-prefixed (0x48 0x65 0x6C). You can also toggle uppercase vs lowercase output.
Does this support UTF-8 and Unicode?
Yes. The encoder uses UTF-8, so multi-byte characters like accented letters, Arabic, Chinese, and emoji are correctly converted to their full byte sequences.
Can I decode hex back to text?
Yes. Switch to the Hex to Text tab to decode. You can also use our dedicated Hex to Text Converter for more options.
What is text to hex used for?
Text to hex encoding is used in web development for URL encoding, in networking for packet inspection, in programming for byte-level string manipulation, and in security for analysis and debugging.
Is my data safe?
Yes. All encoding runs entirely in your browser via JavaScript. Nothing is sent to any server or stored anywhere.
