UUID Generator
Generate v1, v3, v4, v5, v6 & v7 UUIDs in bulk.
This free UUID generator creates unique identifiers (also called GUIDs) following the RFC 4122 / RFC 9562 standards. Pick a version, generate one or up to ten thousand at once, and apply uppercase, curly-brace or hyphen-free formatting. UUIDs are created with your browser's securecrypto API — nothing is sent to a server.
Which version?v4 is fully random and the common default.v7 embeds a Unix timestamp so IDs sort by creation time — ideal for database keys.v1/v6 are time-based (v6 reorders v1 to be sortable).v3/v5 are deterministic: the same namespace and name always produce the same UUID (v3 uses MD5, v5 uses SHA-1).Nil and Maxare the reserved all-zero and all-one values.
