How to use Nano ID Generator

Generate compact, URL-safe random identifiers with browser cryptography.

What to provide

Leave empty for the standard URL-safe alphabet, or provide 2–128 unique characters.

  1. Enter the optional value described above, or leave it empty to generate new values.
  2. Choose the options that match your intended result.
  3. Select “Run tool” or press Ctrl/Command + Enter, then copy, download, or move the result back into the first input for another pass.

What the result means

One identifier per line.

Privacy and safety

This utility is loaded as browser code and processes your input only in this tab. OmniCastConverter has no upload endpoint and never stores your content, filenames, tokens, or secrets. Generated markup and code are shown as inert text and are never executed.

Limitations

  • Security depends on choosing a sufficiently large alphabet and length.
