UUID Generator (Generate random UUID v4 / GUID values, one or in bulk)

A UUID (Universally Unique Identifier), also called a GUID, is a 128-bit value formatted as 32 hex digits in five groups (e.g. 550e8400-e29b-41d4-a716-446655440000). It's designed so two randomly generated UUIDs are, in practice, never the same.

Version 4 (random) — the most commonly used UUID version, generated using the browser's built-in cryptographically secure random number generator (crypto.randomUUID()), not a predictable or timestamp-based algorithm.

Yes — set the quantity to generate up to 100 UUIDs in one click, with options for uppercase letters and removing hyphens, then copy them individually or all at once.
