What is UUID Generator?

UUID (Universally Unique Identifier) is a 128-bit standard format used whenever a globally unique identifier is needed — such as database primary keys, file names, or session IDs. This tool uses the browser's cryptographic random number generator to instantly produce UUID v4 values with an extremely low collision probability. You can generate up to 50 at once, with options to convert to uppercase or remove hyphens.

How to Use

  1. Select the number of UUIDs to generate from the dropdown (1, 5, 10, 20, or 50).
  2. Check the Uppercase or No dashes options as needed.
  3. Click the Generate button to instantly create the UUIDs, then use the copy button to copy all of them to your clipboard.
