Random String Generator

Random Strings is a free tool that runs entirely in your browser, with no data ever sent to a server. Generate a list of random identifiers or codes, with the character set of your choice.

What it's for

Generate test identifiers, promo codes, or temporary keys, when a UUID is too long or a specific format (only uppercase letters and digits, for example) is required.

What this tool does not do

This tool only applies the calculation described, with no check on the context of use. No limit is set by the tool itself; the only constraint is your device's memory.

Frequently asked questions

Should I use this tool for a password to remember?

Prefer the password generator instead, which shows the result's strength and excludes ambiguous characters.

Is my data sent to a server?

No: the text you type or paste is processed entirely in your browser, on your device. It is never transmitted to a server.

Do I need to create an account or install anything?

No: the tool works directly in this page, with no sign-up and nothing to install.
