About Text to HEX Converter Tool
Published: Last Updated:
Text to HEX converts each character to its two-digit hexadecimal ASCII code. This is the format used in hex editors, network packet dumps, and byte-level data inspection. 'Hello' becomes '48 65 6C 6C 6F' — each pair is the hex encoding of one character byte.
Key Features
- Converts text to space-separated hex bytes (2 digits per char).
- Output optionally with or without spaces, with 0x prefix.
- Runs in your browser.
How to Use the Tool
- Enter text.
- Hex bytes appear for each character.
- Copy in the format you need.
Core Benefits
- Understand raw byte representation of strings.
- Useful for network analysis and hex editor work.
Common Use Cases
- "Hello" → 48 65 6C 6C 6F.
- Inspecting raw byte content of a string in a hex editor.
- Writing hex-encoded strings in C/Python: "\x48\x65\x6C\x6C\x6F".
Pro Tips
- Hex 48=H, 65=e, 6C=l, 6C=l, 6F=o. "Hello" is 5 bytes = 10 hex digits.
- Python: "Hello".encode("ascii").hex() = "48656c6c6f"
