Generate unique identifiers (UUID v4)
UUID (Universally Unique Identifier) is a 128-bit number used to identify information. This tool generates UUID v4 (random) identifiers.
A UUID (Universally Unique Identifier) is a 128-bit number used to uniquely identify information in computer systems. The probability of duplicates is extremely low, even when generated by different systems.
Our tool generates UUID version 4 (random), which creates identifiers using random numbers. It's the most commonly used version for generating unique identifiers.
UUIDs are commonly used as unique identifiers for database records, API keys, file names, session IDs, and any other place where you need to ensure uniqueness without coordination.
The probability of generating duplicate UUIDs is extremely low. With 128 bits of randomness, you'd need to generate billions of UUIDs to have a significant chance of a collision.
