UUID Generator

UUID stands for Universally Unique Identifier. It's a 128-bit identifier that is virtually guaranteed to be unique across time and space. UUIDs are commonly used in software development for database primary keys, API tokens, session IDs, and other scenarios requiring unique identifiers.

This tool generates UUID version 4 (random UUIDs), which are created using random or pseudo-random numbers. Version 4 UUIDs are the most commonly used type and are suitable for most applications requiring unique identifiers.

Yes! You can specify how many UUIDs you want to generate (from 1 to 100). All generated UUIDs are displayed in a list that you can easily copy individually or all at once.

While UUIDs are designed to be unique, the probability of generating duplicate UUIDs is extremely low (approximately 1 in 5.3 × 10^36). For practical purposes, UUIDs can be considered unique. The generator uses cryptographically strong random number generation when available.

You can click the "Copy" button next to any UUID to copy it to your clipboard. Use the generated UUIDs in your database schemas, API endpoints, configuration files, or anywhere you need a unique identifier.

No, UUIDs are generated entirely in your browser and are never stored, saved, or transmitted to any server. Each time you generate UUIDs, they are created fresh using secure random number generation.
