NanoID exists because database auto-increment and 36-char UUIDs are overkill for most identifiers. A short URL-safe string identifies a paste, a job, or a doc without leaking counts or padding URLs.
Generate URL-safe NanoID-style random IDs at any length, from short link-style tokens up to collision-resistant sizes. Tune the length to the population, and you get compact IDs that play nicely in query strings.
Try it now: open the free tool, runs 100{ddff9936f8333f09603555df7bd6492034f3a4a35de784276d3cf3d66166a113} in your browser.
Bottom line: choose length by collision risk, shorter is not always better.
