About these tools
A QR code is a grid that encodes text — nothing more. These tools build that text in your browser (a URL, a WiFi join string, a vCard) and hand it to a QR encoder running locally, so the code exists the moment you generate it with no server round trip, no account, and no expiry.
That local-only design matters most for the WiFi and contact card modes, where the payload can include a password or a phone number. Since nothing is uploaded, that data never leaves the device you typed it on.
FAQ
Do these QR codes expire?
No. Each code encodes your content directly rather than redirecting through a link this site controls, so it keeps working even if this site is offline.
Is my data uploaded when I generate a QR code?
No. Generation happens entirely in your browser. The tool page shows a live network monitor confirming zero bytes are sent.
