UUID v4 Generator
Create one or several random version 4 UUIDs, copy a single value, or copy the complete batch as newline-separated text.
Version and variant bits
A UUID v4 contains 122 random bits plus fixed bits that identify the version and RFC variant. Its familiar text form uses 32 hexadecimal digits in five groups: 8-4-4-4-12.
Random UUIDs are intended to make accidental collisions extremely unlikely, not to hide information. They should not be treated as passwords, access tokens or proof of identity.
