About this tool

A UUID (Universally Unique Identifier) is a 128-bit identifier designed to be unique across space and time without requiring a central authority. Our UUID Generator creates cryptographically random UUID v4 identifiers using the Web Crypto API, ensuring true randomness. UUIDs are used as database primary keys, API request identifiers, session tokens, file names, and distributed system identifiers. The generator supports bulk creation of up to 100 UUIDs at once, uppercase formatting, and dash removal for compact representation. The probability of generating two identical UUID v4 values is approximately 1 in 5.3 × 10^36 — effectively zero for any practical application. For database performance, consider UUID v7 (time-sorted) which provides better index locality than random UUID v4.
