About Random String Generator

Generate random strings for API tokens, test data, temporary IDs, or any use where you need unpredictable character sequences. You control the length and character set; generation runs in your browser.

Frequently Asked Questions

Are the strings cryptographically random?
Yes. The tool uses the Web Crypto API (crypto.getRandomValues) so each character is chosen with secure randomness.
Can I use this for passwords?
You can, but for real passwords we recommend the dedicated Password Generator tool which is designed for that purpose.
Is my data sent to a server?
No. Strings are generated entirely in your browser. Nothing is uploaded.
