Byte to String Converter
Convert a list of decimal or hex byte values into a readable UTF-8 string, or convert text into its byte representation. Runs entirely in your browser.
🔒 This tool runs entirely in your browser. Your files are never uploaded to a server.
Separate byte values with spaces or commas.
How the byte/string converter works
- Pick a direction: Bytes → String or String → Bytes.
- Choose whether byte values are shown in decimal or hex.
- Type or paste your input and read the converted result instantly.
FAQ
What byte formats are supported?
Enter byte values as decimal (0-255, space or comma separated) or hexadecimal (with or without a 0x prefix) - just toggle the format switch to match your input.
How is text converted back to bytes?
The text is encoded as UTF-8, and each resulting byte is shown as either a decimal number or two-digit hex value, in order.
Does this handle Unicode characters?
Yes - multi-byte UTF-8 sequences for emoji and non-Latin characters are decoded and encoded correctly, not just single-byte ASCII.
Is my data uploaded anywhere?
No - all conversion happens locally in your browser. Nothing is sent to a server.
What happens if I enter a byte value outside 0-255?
It's flagged as invalid - decimal byte values must be between 0 and 255 (00-FF in hex), since that's the full range a single byte can represent.
