A signal lamp for the modern age — turn a link, WiFi network, or message into a QR code. Free, no sign-up, no watermark, and codes never expire.
🔒 Generated in your browser. What you encode is never sent anywhere.
Scanning the code joins the network — great for guests. The password stays inside the printed code, not on any server.
Pick what the code should do — open a link, join a WiFi network, start an email or phone call, or just show some text — fill in the blanks, and the code appears instantly. Download it as a PNG for documents and flyers, or as an SVG that stays crisp at any print size.
Many QR generators are "free" the way gym trials are free: the code they give you is a redirect through their server, so they can track every scan — and when the trial lapses, your printed codes die. The codes made here encode your actual content, directly. They work forever, nothing is tracked, and the generator itself runs entirely in your browser — the WiFi password you type never leaves this page. Save the page and it works with no internet at all.
