About this Text to Hex
Text to Hex converts each character into a hexadecimal byte representation. This is useful for debugging encodings, preparing test data, or inspecting byte values.
For simple ASCII text, output is straightforward (A → 41). For non-ASCII characters, output may reflect JavaScript code units rather than UTF-8 bytes.
- Process text data quickly without external tools
- Transform content for development workflows
- Clean and format text for analysis
- Enable Auto to transform as you type
- Upload text files directly from your device
- Download the result when done
FAQ
No. Everything runs locally in your browser. Nothing you paste is sent to a server.
After the page loads once, it will typically keep working offline (unless you hard refresh with no cache).
No. Your input stays in your browser. Only optional preferences like theme or language may be stored.
Any plain text. You can paste text directly into the input box.
Each character becomes a hex value, typically two hex digits per byte, separated by spaces for readability.
Not necessarily. Many implementations convert JavaScript code units. For true UTF-8 byte output, you would need UTF-8 encoding logic.
Yes. Use Hex to Text. ASCII text will round-trip cleanly in most cases.
