Privacy details

UUID generator processes your input in this browser. Inputs and results are excluded from analytics. Recent tools save tool names, visit counts and last-visit times. Saved tools store only their names. Draft saving is optional and stays on this device; delete saved text with the draft controls. Loading text from a URL is optional and contacts that server; its URL and your IP address are visible to the server. An optional “Use in” action keeps a handoff in this tab. The next tool removes it on arrival and ignores it if more than a minute has passed.

Copy link includes the inputs you choose to share in the address. Anyone with that link can reopen them. Files and generated results are excluded. Password and key tools share settings only.

Your result

Reset reloads the tool with its starting values and releases open files and device controls. Saved drafts stay on this device until you delete them.

Links include your inputs and settings. Anyone with the link can see them, so leave out private text. Files and generated results are left out; random draws run again.

Using UUID generator

UUID generator uses the browser’s crypto.randomUUID operation. Version and variant bits follow the UUID standard, and no hardware address is embedded.

A worked example

A batch of 5 returns five separate version 4 UUID strings. The version digit is 4 in each identifier.

Before you use the result

UUIDs identify records; they are not passwords or authentication tokens. Random generation does not replace a database uniqueness constraint.
