How to use Nano ID Generator

Set a custom alphabet and length, and the tool generates a compact, URL-safe Nano ID using your chosen character set.

Frequently asked questions

Why use Nano ID instead of UUID?

Nano IDs are shorter (customizable length vs UUID's fixed 36 characters) while remaining URL-safe and collision-resistant, which is why they're popular for short public IDs.

Is this tool free to use?

Yes. This tool is completely free to use with no daily limits and no signup required.

Can I generate more than one at a time?

Most ID generators here support a bulk mode — set the count and copy the whole list at once.
