Unix Path Helper

Inspect, normalize, join, and compute relative POSIX paths, the way os.path or pathlib does.

This tool handles input and primary processing in your browser and is designed not to send the input to QuickKit’s server.

How it works

Normalization is lexical only, exactly like Python's posixpath.normpath and Go's path.Clean: it collapses repeated slashes, drops . components, and resolves .. against the preceding component, without ever touching the filesystem. It cannot resolve symlinks, so the result may differ from realpath when symlinks are involved.
