Frequently Asked Questions
- What input format is expected?
- Space-separated octal values using digits 0–7, like "110 151" which decodes to "Hi". Any token containing 8, 9, or letters is reported as invalid instead of producing wrong output.
- How is octal different from hex encoding?
- Both represent the same byte values in different bases — octal uses digits 0–7 (base 8), hex uses 0–F (base 16). Hex is more common today; octal survives mainly in Unix permissions and escape sequences.
- Is my data private when I use this tool?
- Yes. This tool runs entirely in your browser using client-side JavaScript — nothing you type is transmitted to, logged by, or stored on any server. You can safely process confidential text, tokens, or code.
