People reach for QR codes for wedding invitations, restaurant menus, business cards, event posters and packaging. Many online generators watermark the code, require an account, or route your link through their redirect service — which means the code dies if the service does. This one encodes your content directly and permanently, generates it in your browser, and gives you a clean PNG with no strings attached. The first render loads a small open-source library; after that it works offline.
Frequently asked questions
Do these QR codes expire?
No. The QR code encodes your text or URL directly — no shortening service in the middle — so it works forever, as long as the URL it points to stays live.
What size should I use for print?
Download at 1024×1024 for print — sharp on posters, menus and invitations. A printed code should be at least 2×2 cm and scannable from about 10× its width away.
What can I put in a QR code besides a URL?
Any text: Wi-Fi details, contact info, an email address (mailto:), a phone number (tel:), or a plain message.
