UUID / GUID Generator

Generate UUIDs right in the browser. Everything runs client-side, nothing leaves your browser.

Supported formats:

UUID v4 (RFC 4122) - the classic random format. 122 bits of randomness, virtually zero chance of collision
UUID v7 (RFC 9562) - newer time-based format that embeds a Unix timestamp in milliseconds, so you get natural chronological sorting while still being unique
