About Text to Octal
The Octal tool converts text to the octal (base 8) value of each byte, space-separated, and back. Octal uses digits 0–7.
How it works: text is encoded to UTF-8 bytes, then each byte is converted to base 8. Decode reads each octal number back into a byte and reassembles UTF-8 text.
Octal was common in early computing and still appears in Unix file permissions (chmod) and some escape notations. This tool helps convert text to/from octal notation.
FAQ
Can this Text to Octal tool both encode and decode?
Yes. This is a single page with a toggle — use Encode mode to transform text, and Decode mode to reverse it. No need for two separate pages.
Is my data sent to a server?
No. Text to Octal is processed entirely in your browser. The text you enter never leaves your device.
