What the Text to Hex Converter does
Encode text as hexadecimal byte values for inspection, testing, and data exchange.
Type or paste words and see the exact byte values a computer stores for them.
Why the Text to Hex Converter is useful
Hex output makes the underlying bytes of a text string visible for debugging and protocol examples.
When you are checking encodings or writing protocol examples, seeing the bytes removes guesswork about what is actually stored.
Also known as: text to hex, hex encoder, free text to hex converter, online text to hex converter, text to hex converter online free, text to hex converter tool, best text to hex converter tool.
How to use the Text to Hex Converter
- 1
Type the text
Enter the text you want encoded and pick whether output should be spaced, comma-separated, or continuous.
- 2
Choose options
Enter text, choose an encoding, and copy the generated hexadecimal bytes.
- 3
Copy the bytes
Verify a short familiar word first so the byte order is what you expect, then copy the full result.
Key features
- UTF-8 byte encoding
- Optional separators
- Uppercase or lowercase output
Benefits
- Produces predictable byte-level representations for technical workflows.
- Non-ASCII characters encode as their true multi-byte sequences, not approximations.
Real-life use cases
Protocol docs
Build a worked example for a spec that lists the bytes on the wire.
Encoding checks
See how an accented name differs between encodings before storing it in a database.
Tips for the best results
- Use UTF-8 unless the receiving system explicitly expects another encoding.
- Note the encoding next to the output; the same characters encode differently in UTF-8 and UTF-16.
Conclusion
Record which encoding produced the output, because the same characters encode differently in UTF-8 and UTF-16 and the bytes are meaningless without that note.
Frequently asked questions
What is hexadecimal?
- A base-16 representation of bytes using digits 0–9 and A–F.
Does UTF-8 support non-English characters?
- Yes, with multi-byte output where needed.
Can I remove spaces between bytes?
- Yes, choose continuous or separated output.
Is the output reversible?
- Yes, decode it with a compatible hex-to-text tool.
Does it encode line breaks?
- Yes, line breaks are included as bytes.
Is text uploaded?
- No.
