What is Nano ID Generator?

Nano ID uses a URL-safe alphabet of 64 symbols. This tool generates independently selected characters with Web Crypto and unbiased rejection sampling. The default 21-character length carries up to 126 bits of random information. This is a compatible-style generator rather than the official nanoid library.

How to use this tool

  1. Pick an identifier length between 1 and 256 characters.
  2. Choose how many identifiers to generate, up to 1,000.
  3. Generate, copy, or export results without uploading any data.
