Frequently asked questions

Is this actually random?
Yes. It uses the Web Crypto API's crypto.getRandomValues, the same source browsers use for TLS keys — not Math.random.
Is the password sent anywhere?
No. Generation is 100% local. Nothing is logged, transmitted or stored.
What length should I pick?
For online accounts, 16+ characters with mixed sets is comfortably strong. For master passwords or crypto seeds, 20+ is recommended.
Are my files uploaded to a server?
No. Files are processed directly in your browser using JavaScript and WebAssembly. Nothing is uploaded to our servers, so your documents never leave your device.
Does it work on mobile?
Yes. The tools run in any modern browser on desktop, tablet, or mobile (Chrome, Edge, Safari, Firefox). Very large files may be slower on low-end phones.
