How to use Hash ID Generator

Enter a number and an optional salt, and the tool encodes it into a short, non-sequential hash ID using hashids-style alphabet mapping — good for hiding database IDs in URLs.

Frequently asked questions

Can this be reversed back to the original number?

With the same alphabet and salt used to encode it, yes — that's the point of hashids: a reversible, non-sequential stand-in for a numeric database ID.

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.
