Version 4 UUIDs are generated using random or pseudo-random numbers, making collisions practically impossible (1 in 2¹²² probability).
UUIDs are used extensively in databases (primary keys), distributed systems (avoiding ID conflicts), session tokens, file naming, and API request tracking. This generator uses the Web Crypto API for cryptographically secure random generation.
A UUID (Universally Unique Identifier) is a 128-bit identifier guaranteed to be unique across space and time. UUID v4 uses random numbers, making collisions practically impossible.
Yes. The generator uses the Web Crypto API (crypto.randomUUID or crypto.getRandomValues) which provides cryptographically secure random numbers.
Yes. Set the quantity (up to 100) and click Generate to create a batch of unique UUIDs that you can copy to your clipboard.
