Privacy details

Random string 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.

Make sample identifiers with the characters you need

Choose a length, a quantity and a character set. Repeated characters in your set are removed before drawing so each distinct character has the same chance. Each position is chosen independently.

A worked example

A character set containing only X produces XXXXX at length 5. A set of AB can produce AA, AB, BA or BB at length 2.

Before you use the result

Length counts Unicode code points, so a joined emoji may contain several positions. Outputs can repeat. Use the password generator for account passwords and the UUID tool for standardized identifiers.
