About UUID Generator
Generate cryptographically random UUIDs in v4 (fully random) or v7 (timestamp-prefixed, sortable) format. UUIDs are essential for distributed systems, database primary keys, and tracing identifiers. This tool uses the Web Crypto API — the same secure randomness source used for session tokens. Bulk mode supports up to 1000 UUIDs at once.
