UUID Generator
Generate random UUID v4 identifiers online.
UUID Generator creates universally unique identifiers (UUID v4) using cryptographically secure random numbers. UUIDs are 128-bit identifiers commonly used as database primary keys, session tokens, and distributed system IDs.
Features
- Generate UUID v4 (random)
- Bulk generation (1-100 at once)
- Cryptographically secure (crypto.randomUUID)
- Copy individual or all UUIDs
- Auto-generates on page load

What is a UUID?
A UUID (Universally Unique Identifier) is a 128-bit number used to identify information in computer systems. UUID v4 uses random numbers, making collisions extremely unlikely.
Is UUID v4 truly unique?
While not mathematically guaranteed, the probability of generating two identical UUID v4 values is approximately 1 in 2^122, making collisions practically impossible.
