What hex formats are supported?

The tool accepts space-separated bytes (e.g. 48 65 6c 6c 6f), continuous strings (e.g. 48656c6c6f), and 0x-prefixed values (e.g. 0x48 0x65 0x6c). Commas and newlines between bytes are also handled automatically.

What is the difference between UTF-8, ASCII, and Latin-1?

ASCII covers the first 128 code points (English letters, digits, basic punctuation). Latin-1 (ISO-8859-1) extends that to 256 code points covering Western European characters. UTF-8 handles the full Unicode range and is the correct choice for most modern text including emoji and non-Latin scripts.

What happens when the bytes are invalid for the selected encoding?

The tool shows an error and clears the decoded output. Try another encoding — for example, Latin-1 data decoded as UTF-8 may be invalid for bytes above 0x7F.

Is my data sent to a server?

No. All conversion happens entirely in your browser using JavaScript. Nothing is transmitted.

What is the maximum input length?

There is no hard limit. Performance may decrease for inputs larger than a few megabytes because the browser processes everything in memory.

Can I convert multi-line text to hex?

Yes. In Text → Hex mode, newlines are encoded as their hex equivalents (0A for LF, 0D 0A for CRLF) just like any other character.

Summary

This tool converts hexadecimal strings into human-readable text and back again. It handles all common hex formats — space-separated bytes, continuous strings, and 0x-prefixed values — and lets you choose between UTF-8, ASCII, and Latin-1 (ISO-8859-1) character encodings. Everything runs in your browser with no data sent to any server.

How it works

Paste or type your hex string (or plain text) into the input field.
Choose the direction: Hex → Text or Text → Hex.
Select the character encoding: UTF-8, ASCII, or Latin-1.
The output appears instantly as you type.
Use the Copy button to copy the result to your clipboard.
Click Swap to reverse the conversion without re-entering text.

Use cases

Decode hex-encoded payloads from network packets or log files.
Inspect binary file headers represented as hex strings.
Encode text to hex for debugging protocols or embedded systems.
Convert 0x-prefixed hex literals from source code to readable form.
Decode Latin-1 encoded legacy data from older databases.
Verify or generate hex-encoded strings during API development.
Understand hexdump output from tools like xxd or hexdump.
Quickly test encoding round-trips (text → hex → text).
