Permission Converter

Symbolic Notation

Nine characters: r, w, x or - for owner, group, and others.

Numeric Notation

Three octal digits from 0 to 7.

How It Works

Each permission digit is the sum of read (4), write (2), and execute (1). For example 7 = rwx, 6 = rw-, and 5 = r-x.

The nine symbolic characters map to three triplets: owner, group, and others. The two notations are converted back and forth instantly as you type.

All conversion happens locally in your browser.
