Which tool should you use?
- Share a link, Wi-Fi login or contact by camera: QR Code Generator makes a QR code you can download as PNG or SVG for print.
- Create a new password or passphrase: Password Generator uses your browser’s cryptographic random generator and shows how strong the result is.
Typical workflows
Both tools have the same privacy promise: what you type into them, such as your Wi-Fi password, never leaves the page. A QR code is just a picture of the text you entered, so anyone who scans it can read that text. For a guest network, print a Wi-Fi QR code; for your own accounts, use a different generated password on every site and keep them in a password manager.
Frequently asked questions
Do the QR codes expire?
No. They contain your text directly rather than a redirect link, so they work as long as the destination does.
Are generated passwords stored anywhere?
No. They exist only on the page until you copy them. Reloading the page clears them.
