Standard lowercase gives the canonical 8-4-4-4-12 form. Uppercase, compact (no hyphens), and brace-wrapped formats are available for systems that expect a different casing or delimiter convention.
Click Generate. All values are created locally using the browser's crypto API, so the output is cryptographically random and never sent to a server.
Click any individual UUID to copy it, use Copy All for the full list as newline-separated text, or download a .txt file when you need to store the batch for later.
