Convert Octal to Binary
Unix file permissions and some legacy systems represent values in octal. When you need the binary form — for example to inspect individual permission bits — this chain decodes the octal input and encodes the result as binary. Each octal digit maps to exactly three binary digits, making the conversion lossless and easy to verify by hand.
What it solves
Decode an octal (base-8) number into its numeric value and re-encode as a binary string.
Input → Output
