How to use Text to Octal

Type your text, and the tool encodes each character as an octal (base 8) number.

Frequently asked questions

What is octal?

Base 8 — uses digits 0–7. Commonly used in Unix file permissions (chmod 755) and older systems.

How is 'A' encoded in octal?

'A' is ASCII 65 decimal = 101 octal.

When is octal used today?

Unix/Linux file permission bits use octal: rwx = 7 (4+2+1), r-x = 5 (4+1).
