Numeric vs symbolic

Numeric permissions use octal digits like 755, while symbolic permissions use characters like rwxr-xr-x to describe read, write, and execute bits.

Special bits

The converter supports optional special bits in 4-digit notation (setuid, setgid, sticky) and their symbolic forms with s/S and t/T markers.

When to use this

Useful during deployment, shell scripting, Docker setup, and debugging permission issues on files and directories.
