Each character has a Unicode code point. Octal is base 8 — it represents that number using digits 0-7. Computers historically used octal because three binary digits map to one octal digit (000=0, 111=7).

What is Text to Octal?

Text to Octal turns text into base-8 byte values. Each character becomes a three-digit octal number, the kind you see in Unix permissions and C escape sequences.

How to use

Type or paste the text you want to convert to octal in the input field.
Select formatting options: delimiter style (space, backslash prefix) and whether to pad with leading zeros.
Copy the octal output for your scripts or docs. Flip to reverse mode to convert octal back to text.
